The buzz about scrapers…
Lately, talk of the cabinet scraper and the frustration that this little tool inflicts on a character has created some buzz in the LJ community. This simple, inexpensive, and very effective tool also frustrates me, but for a different reason. I see many people missing out on the joy of using this tool because they are fed too much information that clouds the simple truth.
On the other hand…
On one hand I appreciate the histories and detailed accounts of filing, honing, burnishing, and turning the burr. On the other hand, the cabinet or card scraper is made overly complicated.
When I share my method of sharpening a cabinet scraper with other woodworkers, I am most often discounted and pooh-poohed. It’s near heresy because it is not mystical and complicated enough. It does not support the shroud of mystery around some lost art of the craftsman which elevates him to the level of mythical proportions.
Pulling down the shroud of mystery…
There is always more than one way to perform tasks in the shop, but here is how I sharpen my scrapers. This post may look long but it is more photos than text.
Here is a look at the collection of scrapers that I use almost everyday that I work in the shop. I use them quite often in my remodeling as well.
I have no preference of any of them. They are different sizes but they are all basically the same thickness, about 1/32” thick.
There is one card that is thinner which gets used the least. I have enough control of the thick scrapers to perform some of the finest work on veneer and inlays. Here I display the difference in the thickness of the scrapers.
Workflow and sharpening…
When I am working at the bench and need to use my scrapers, I leave my mill file clamped in the bench vise just like this.
I will scrape my project on one bench and then turn around to the other bench to stroke the card a few times to whip it back into shape. I do not use a jig, I simply hold it by hand at a 90 degree angle on the file. To sharpen I stroke it the full length of the file 3 to 4 times, that is all that is needed. Then I flip it and do the other side. This is exactly how I hold it.
Here is a tip…
One thing I find important is keeping the file clean from the file shavings. I keep compressed air handy to blow off the file. You can feel if the shavings roll under the scraper, this is a sign that it needs to be blown off.
What’s your angle?
The easiest way to find the working angle is to hold the card at 45 degrees to the surface. Then stand it back up toward vertical a little more, no more than 1/4 to 1/3 the distance. I don’t get hung up on the angle in degrees, it is really by feel. You will get the feel of it as you vary the angle and pressure until it starts to produce fine shavings.
Place your thumbs in the center towards the bottom of the scraper. You can use different areas of the cutting edge by moving the location of your thumbs, thereby applying pressure where you want. You may also pull the scraper applying pressure to the back with your fingers.
This is basically what it will look like.
Here is another view showing some real cabinet scraper action on a piece of reclaimed doug fir flooring.
Here is the flooring with a good bit of scraping done. This piece of wood flooring had a finish on it and sheetrock mud from a remodel project. The cabinet scraper was sharp enough to cut through all of this and make some of the finest shavings.
Here is the result of my sharpening method on a piece of curly maple. This is a difficult piece of wood to plane by hand or machine, but look at the finish and the fine curly shavings.
The next photo shows the scraper results on a piece of Brazilian cherry with a difficult grain pattern. Notice that once again I get consistently fine “angel hair” shavings.
My last photo shows a piece of baltic birch ply that has a maple veneer that I applied. I have total control to scrape the veneer without cutting through it and yet get some nice shavings.
The proof is in the pudding…
Well, there you have it. I sharpen my cabinet scraper with a few strokes on the file and nothing more. I sharpened the scraper between each piece of wood but these are true results for each.
I have no preference as to which cabinet scraper that I use. The cheap Stanley scrapers work just as well as the more expensive Sandvik scrapers.
A balanced point of view…
I will let you know that the cabinet scraper is followed by a random orbital sander in my workflow. I never use the scraper with the intention of the wood surface going straight to finish.
This level of sharpening is very easy to master and then you may find yourself wanting to precede to the next level. I am very satisfied with the performance of my scraper at this level and do not desire to go any further. If you look at my portfolio you can be sure that the cabinet scraper was used in every project and the results speak for themselves so I can stand by my method.
May the shroud of mystery be pulled back and the great Oz be exposed…it is that simple.
Peace, Love, and Woodworking

Todd, this is exactly how I do it. If I’ve misplaced my file (again) I just throw some 150 grit paper on the chunk of granite I use for a honing plate and sharpen my scrapers there. And I completely agree … every time I mention this method, someone starts in about some obscure difference between two types of burnishers.

Todd I can understand the desire to pull back the shroud of mystery … BUT … with that you destroy one of the mystiques of woodworking. These secret practices are necessary to maintain the illusion of superiority. If you continue to expose the simplicity of some of these things then people like myself will be forced to fall back on the quality of our work for the ooohs and ahhhhs. I’m not sure I’m up to that. ;-)
Yet, it’s a good explanation and I may even pull out my card scrapers and give it another try.

Nice post, Todd. I have always assumed that burnishing was a part of the sharpening process. I will try just putting an edge on with the mill file and see how it comes out.
By the way I am curious how so you sharpen the curved scrapers. I have used set at times, reluctently, since I can’t see a way to easily sharpen them, as you can the straight scrapers.

Amen brother! I feel the same with sharpening methods for plane irons and chisels. In my opinion try a few methods fine what works best for your application and stick with it the more your do the better you get at it and therefore is the best for you.
I cant afford $ 300 Japanese water stones or fancy machines but with a .99 cents piece of 600 grit wet dry sand paper and my trusted slab of marble I can achieve a mirrored razor sharp finish on any blades.

Another good one, Todd. I’m all for removing that mystery as well. I do run a burnisher on the edge but it is not very technical. I use a small file that I stick in a saw kerf in a piece of Oak. Keeps the angle at 90 and is quick and easy. Keep ‘em comin’, pardner.

Here is a decent article that agrees with you Todd.
“The conventional wisdom is that the steeper the hook, the more aggressive the tool (15° is supposed to be for removing paint; 0° is supposed to be for marquetry). But the truth is, we could get excellent results with all the edges. You could get the wispiest shavings with a 15° hook if you used light pressure. In fact, the only scraper that seemed to perform significantly different is one that I prepared with no hook. That one took only light shavings.”
So it’s different from a scraper with a burr but still an effective tool.

Great blog, clear and to the point.
Unlike yourself, I prefer to use a burnisher to get that turned edge. But as you said do not get hung up on the angle, for every piece of wood is different, even the same board, along its length. when you get that first good shaving comming off the scraper card, you will know what it feels like and then know what to aim for in the future.

Great info.
I’m with Tony on this issue.
I’ve been using cabinet scrapers for four decades.
The burr/no burr controversy isn’t a categorical position for me – it’s a continuum of possibilities.
Both work, but sometimes one way works better than the other for a particular kind of wood, desired finish or preferred technique. Just like the cabinet scrapers big brother, there are many different kinds of planes, each with their own specialized purposes.
Until recently, I’ve always made my own scrapers out of spent saw blades or other appropriate pieces of steel.
Lee Valley makes them too easy to obtain – I like that.
My personal techniques tend to vary from “conventional wisdom.”
Since I lean toward Japanese hand tools that tend to work on a pull stroke, rather than a push stroke; I prefer to scrape by pulling. However, I’m “ambi-directional” as needed for a particular situation.
I’ve even tried using mussel shells from our local river, just like some of my ancestors, for wood scraping.
Burr-less, of course. I’ll stick with modern steel for now. :)
I teach rustic wood crafting, and my students are amazed at the differences in how well a properly setup scraper works; burr or no burr. Add a little bit of good technique to the mix and the humble cabinet scraper becomes a favored tool.

Todd,
This is great! I will have to try your method as I love any excuse to use my card scrapers. To try different techniques in woodworking is a good thing. All too often we become too comfortable in doing things the first way we were taught and don’t venture to try new techniques that may be easier, safer or yield better results then what we currently use.

I really appreciate the feedback from everyone.
I found that I did not need to go any farther than what I have shown here in the blog to get great results.
This entry should encourage frustrated individuals to give it a try again and get the card scraper functioning in their own shop.
The various wood samples support the success of my method in that it provides results in various types of difficult wood. I also use this on veneer and inlay with no damage and great results.
I believe that many will have success with this and when they feel comfortable, start exploring the next level of card scraper sharpening. I certainly encourage this.
I push and pull my scrapers as well. I did not really cover this but I plan on working on a video to show more.

yea talking about scrapers is worse than talking about politics sometimes. there is so many different opinions on how to sharpen or use the tool. you hit it on the head with this post. people over analyze the sharpening method. it took me forever to get it too. i was doing all kinds of fancy things to get the burr. and i got nothing more then a handfull of lousy dust. ofcourse now after 4 years of diddle pissing around with fancy methods of sharpening i have learned and mastered the simple technique of it. i do it verry simillar to the way you do it. only diference is i take a shiny screwdriver and turn the burr a little more. great post todd. love the topic. i hope people try the easy method.
i agree that it is a wonderfull tool and it is ireplaceable. its perfect to use for dried glue, for figured woods, defects, knots, and inlays i also use it allot on joinery were end grain is visible. a scraper shines up end grain real nice. but i still dont have me one of them goosenecks. do you use those often or is it one of those tools that can only be used for one purpose only. like cove moulding

Mike,
The curved ones do not get used too much. I used the gooseneck when I made the custom cove on my bookcase for example.
My card scraper does not get as hot as it used to. I move the pressure point on the card back and forth to utilize more of the cutting edge on each face. A cooler card scraper is a positive side effect from this technique.

Have you just built a better mouse trap?
At the angle your cutting point engages the wood you aren’t ‘slicing’ like a traditional scraper, you’re getting more of a “compression peel”? (Someone probably has a better term for that action.)
This is brilliant in it’s simplicity, and given the results, it’s obviously effective and far more applicable for the majority of tasks. This makes an otherwise frustrating tool easily useable for a broader range of people and applications.
Do we need to refer to this as the new ‘Clipper’ method?

Quixote – I understand what you are saying about the compression peel, but it does not matter to me. The card scraper is part of my workflow that ends in using the random orbital sander before finishing.
My feather-like shavings do come off quite readily and so I am happy with the required effort and the result.
The finish that it leaves is quite nice on all the material that I scrape. I demonstrated on difficult materials that would challenge the scraper to show how effective this method is.
I openly admit that burnishing the scraper would leave an even nicer finish, but it is pointless to me because I finish with the sander.
I have to get on a video – time is always the issue.

todd – thanks – I’ll have to give this method a shot.
question: what grits do you use when finishing with the sander?
also, what sort of file is it? looks like single cut, but is it a “fine” grade?
also, I’ve been wondering on the importance of a burr, since fresh cut glass gives the nicest scrapings I’ve yet to see, and that certainly has no burr, it’s just super sharp.

AronK – This is a great question and I should have included the information in text (I will add) and in the video.
I use either a 10 mill or 12 mill bastard file – single cut. Both work equally as well for me.
Sharpening definitely generates a burr because I can feel it on the edge. It is there and I am certain that this must be doing the cutting. I ignore all other directions on sharpening because they say to get rid of this burr and burnish a hook on it. It is obvious that this method is working for me as it is.
I finish to 150 or 180 as needed. On paint grade projects you can get away with 120 or 150 because the paint covers so well. I hardly ever go to 220.
Some wood seems to smooth out fine with just 150. Sometimes I need to go to 180. I do not like to spend any more time sanding than I have to. I can look at the wood closely and experience tells me if I need to go one more step. To be sure you can just go ahead and take it to 180 and I am certain that would be sufficient.
I have a great reputation for finishes so I must be doing something right.
I have debated with other woodworkers about how legitimate my sharpening method is and, ironically, the guys that use the burnisher method still finish out with a random orbital just like me.

AaronK – One more thing, I realize that the “experience tells me” answer does not help you much. I would suggest that you sand some samples of wood to various levels from 120 through 220. Then put some finish on them to see how it highlights the swirl marks.
Try various woods too. Try the most common ones that you will be using like oak, cherry, maple, or whatever your flavor is. Try a stain to see how it highlights the scratch marks as well. You may even try some paint to see how the swirl marks read through the coating.
Do not just look at these in a critical raking light, take them in the house and lay them in common areas where a side table would be or on the dining table and just see how they look in a normal lighting situation.
Here is another important piece of information; I use a 6” Bosch random orbital and it has really tight swirl marks and runs at a higher rpm than many other sanders on the market. I own two of these because I can take one to the field and leave one in the shop. While in Ohio I had to have the motor brushes replaced and I did not have the back-up. I do not like using a 5” because they are very slow compared to the 6” so I bought a Ridgid 6” RO sander with the intention of leaving it in my brother’s shop. The Ridgid runs at a slower rpm with lower orbits per minute and has a larger stroke pattern, even on the fine setting. When I use this sander I always have to finish at 180 and it takes longer than the Bosch.
So the moral of the story is that the sander you use may make a difference.

I use two files, either a single cut 10 or 12 mill bastard file. Both work, one just cuts faster the other and wears the cards down more quickly.
It is simply known as a “metal file” in generic terms. Every hardware store has them. I buy the larger ones to give me more file surface to work with.
You can see the file in the photo. If you ask at the hardware store I am sure that they can point it out.
Single cut means that there is only one diagonal direction of the file teeth. It is not criss-crossed in the pattern and it will only cut in one direction, that is when pushed.

Todd,
Thanks for making those distinctions. Since I posted my question I was in town and stopped at The Homeless Depot where I bought a general purpose “mill file”. The good news is that it turns out that this is a single cut model. However, this may be too fine for our purpose now that I have read your response. It is rated as a 200 mill file. I think I will keep it as my file collection here is paltry. It can be put to some good use in the future. I will try it with your technique and see if it makes any headway setting up the scraper. If not, I’ll get a coarser model and try that. If nothing else I will learn something about files and have a couple of new ones on hand to use.
Thanks,
