I went back and forth…agonizing for a few weeks actually…..do I get these? do I not??...and on and on. Finally…after more than enough study I went for it and hit the pay button….lol. These are not cheap.

These are DMT diamond stones 10×3 extra coarse, coarse, fine and extra fine. I also purchased a bench strop with green honing compound.

I made a little plywood movable work station, routed out the relieved areas with my stanley 71 hand router (that was a workout…lol) and proceeded to set them in. Then I anchored in my strop and it all works very well and in order of use.

This sharpening setup was of course one of the many things I picked up from Paul Sellers…and the verdict so far is…...WOW!...LOL

I thought I had decent sharpened chisels…and plane blades…and I think I did have…DECENT….but this exercise…fast and easy will certainly retire any thoughts of fiddlling with stones of any sort.

Now…. there are of course some bad stories about these too….some have actualy ruined the diamonds…etc..

From what I have learned the percentage is high that these will last long with the right care. I use water on them…some use glass cleaner etc…but I have read water is fine too.

Also my shop is a garage…so I actually do take these and store them inside and dry them after use.

I do not woodwork for a living so my sharpening will not need to be everyday.

I would test by taking chisels, plane or spokeshave blades and work them through oak….before a honing session. Then I would proceed to work the blade approx 30-50 reps on each stone, then strop front and flatten the back 30 -50….whatever your feeling is on it….place the blade in or take your chisel ….and friends….haaaa you talk about shavings…....oak gets nice with these blades…... SON!....lol

Picked this cool little sears block plane today…8 bucks! Gave her a whirl….it had an ok sharpness…it cut fairly well. I worked the blade out on these….and I have gossamer shavings and a hissing cut!

I even tried the old goofy lets see if it will take hairs off my arm routine…haaaaa…..I got some smooth arms pretty fast…..lol

My spokeshave works like never before with the same blade I got it with…..for 5 bucks 7 months ago.

These stones can really take that small auction purchase and add some serious firepower to what in the past would have been an ok user that mostly sits out while you reach for your $80 newbie.

So this is my introduction to learning more about sharpening….I guess this was a blog and review…..hahaha…...I hope I am not subject to the penalty box..lol

Ok friends, have fun and if your thinking about using these….they are really pretty impressive.

Take care

Joe

Thanks Joe, been thinking about them myself. What is it with people spray painting planes red? I have seen too many for it to be one guy : )

Very nice Joe. That is probably my ideal setup. I think I’ll have to start saving my pennies. :-)

Very cool Joe, been wondering about those myself. My old oilstone is well-worn, maybe needs an update!
thanks,
Dale

Very nice setup. I like the solid bar diamondstones. You are right on several, I didn’t actually count, but probably all counts. A few years ago I caught the waterstone fever and paid up. I spent more time flattening waterstones than sharpening blades. Now my originally 1.5 inch thick waterstones have lost considerable weight.

Did you know it takes a really flat stone to flatten a waterstone really flat! Another expense.

I discovered that sandpaper on a $5 scrap of granite slabs works just as well. Figures. Still. Then a couple of years ago, I found a set of three DMT diamondstones on clearance at a great price, half off, so curious, I bought them. A red, green, and a 8000 grit. I forget which color goes with which grit.

After two years, they still cut like they did on day one, and still just as flat. The one complaint is the 8000 grit diamond is more course than the 8000 grit waterstone, so this waterstone still gets use. Did you have a similar experience with the 8000 grit diamondstone? It will likely be a long, long time before you buy another stone.

I bought a set of these used off ebay. I bought them because I caught a really reasonable buy it now. I like mine as well. I’ve found myself using them instead of the oil stones 100% of the time.

Love my DMTs, congrats on yours. Picked up the stopping tip from Paul as well, and Wow! is right…

Thanks for the review, I’m using water stones now and the constant flattening is not that fun. I may go this rout some day.
