I know its been beaten like a dead horse, but the scary sharp method sure is quick, easy, and cheap, especially for a beginner.

I got my first set of chisels today and, or course, they need to be sharpened. No fancy chisels here. The $30 set of 4 Irwin bench chisels. I set up my sandpaper 150, 320, 400, 600, 1000, and 1500 grit. The 400 through 1500 is wet/dry. I started flattening the back of the first chisel and was pretty skeptical. By the time I got done with the 1500 it was like a mirror, at least about a 1/2” of it was. I was pretty impressed to say the least. I flattened the backs of the rest of the chisels and switched out all the sandpaper. I don’t know if I really needed to do that the sandpaper didn’t feel all that bad, but I did anyway.

I used a honing guide for the 1/4”-3/4” chisels and went all the way through the grits and they are nice and sharp, I guess. I don’t have much to compare them too since I have never owned chisels before let alone sharpened any. I thought I would give free hand a try on the 1” chisel. It seemed to work just fine and feels just as sharp as the rest. There is no hair shaving going on, I think I need a little more practice before that happens. But, for a first time EVER sharpening ANYTHING the scary sharp method worked great. It took me about an hour and half to sharpen all 4 chisels. Should be considerably faster in the future.

I dug out a scrap of maple and just tried paring away a little with each size and it was pretty effortless. Now I just need to find out how long they keep their edge. I am going to try hand cutting some mortise and tenons to practice and get the feel for the chisels.

Wish me luck.

sounds like a winner!

initial shaping of the chisels does take longer, but with practice even that will take you much faster to accomplish (on future new chisels).

now that you have your chisels shaped properly – each time you want to hone them , you can go straight to the 1500+ grits since you do not need to sharpen them unless they chip/lose bevel for a while. should take you less than a minute per chisel.

To test your blade sharpness try this: pare the end grain of hard maple. if the chisels are sharp – you’ll end up with the cut grains having smooth glass surface – no tears/splinters/dull look – it’ll be shiny!

It will definitely be quicker in the future… You should only have to flatten the backs once and unless you chip them or let them get really, really dull it’s just a touch up. I usually touch them up couple of times during use and right before i put them away

I invested in the Veritas Mark II honing guide because it has a cam adjustment to change the angle by 1% to achieve the micro bevel. Works like a dream with the SSM

Good work Dan. When I took the sharpening class at Highland Woodworking, our instructor, Jim Dillon, said that the sandpaper on glass was the least expensive and easiest way to get into sharpening – but was the most expensive method in the long run due to the cost of the sandpaper.

A good next step for you would be to invest in a set of water stones up through #8000 plus a nagura stone to create a slurry. This is how I keep chisels and plane irons sharp.

As far as how often depends on how much you use them. Good practice is doing it a couple swipes everytime before you do something. This way will only take a few seconds and you can be sure they are always sharp. I havw those irwins and the steel is’nt as good as some name brand chisels. They do run dull rather quickly. If your not in a shop 24/7 those will be fine. Just give them a quick zip each use!

By the way I used the scary sharp method for a long time. I have had no problems…..ever

I have been using a set of Marples Blue handle for some time (same Irwin thing) , and I agree with getneds, the steel is not so good….. So, no matter how good the sharpening method is, the chisels do not hold the sharp edge as other high quality chisels.
