I’m pretty sure you can cut the stones with a diamond coated cut off wheel. They are also used for ceramics.
I used a 3/4 hp wet/tile saw equipped with a 7" diamond blade to cut 3 Wusthof stones… I’d say It did a decent job considering I picked it up for only $20 at a pawn shop.
Awesome guys! Thanks! yeah that’s what i’m hearing is that i can use a tile saw w/ a diamond blade… my brother’s friend has one so I thin that is the route I will go when it comes in.
Check it out! All cut and mounted! Looking forward to using these… 

Very very nice, Josh! How difficult was it to cut them ? And are they consistently thick?
Super easy w/ a tile cutter =) I aimed for about 1/4" thick on the stone thickness… one pair is significantly thinner than that though lol.
Here’s the latest on my SP 120’s…
Hi Josh:
Some questions I think viewers might have:
-
That seems like a lot of dishing for having done only one knife. How long does it take you to lap them back into flatness?
-
How many knives do you think you’d get for each pair ?
-
How many pairs do you think you’d be able to cut from one of the sigma 120’s?
-
Why do I see daylight between the top edges of the stones?
-
Did you use a blank set of blocks from WE or the blocks with the aluminum platens?
-
How is the stone attached to the aluminum backing plate? The tape recommended by WE or adhesive? Something else?
And for me:
Do you only use the AngleCube for stone changes? Why aren’t you using the SWAT’s? Seems like a perfect application for them.
Great questions Tom, thanks!

-
How many knives do you think you’d get for each pair ? Not many at this rate… That’s why I am going to have to find another option or stick w/ the stock 100 diamonds.
-
How many pairs do you think you’d be able to cut from one of the sigma 120’s? I cut 3 pairs. The Sigma Power 120 costs around $25 including the shipping, so this isn’t a bad price, but at the rate they dish, it is.
-
Why do I see daylight between the top edges of the stones? I think there may have been some contamination there or something, like a piece of grit. I will have to check them later to be sure what it is.
-
Did you use a blank set of blocks from WE or the blocks with the aluminum platens? I bought my own aluminum flat stock from Lowes, cut it up, and lapped that before ever attaching these stones to the aluminum. After they were attached to the aluminum backing they were applied to the paddles w/ some 3m double sided tape that I got from Bob Nash.

How is the stone attached to the aluminum backing plate? The tape recommended by WE or adhesive? Something else? I am using what I use on knife handles… G-Flex epoxy.
And for me:
Do you only use the AngleCube for stone changes? Why aren’t you using the SWAT’s? Seems like a perfect application for them.
I only use the Angle cube for initially setting up the angle. After that I know all the angle changes to make automatically when going from stock diamonds, to choseras, to strops. For instance, when using the stock diamonds I have to go 2 dps wider of an angle (on the base bar) when going to the choseras to match the bevel almost perfectly. Then the 800 grit choseras will finish cleaning up the edge to a perfect apex. when i go to strops I know that I have to go 4 dps (on the base bar) less than the choseras if I want a true 2 dps less of an angle than what i had been at.
To Josh:
Thanks for the quick reply. Understood clearly, but now I’m curious… Why did you use epoxy to attach the aluminum to the block? Why not the same tape? I was thinking that you put the stone on the aluminum so you could pry the aluminum off of the block without breaking the stone.
Speaking of knife handles… I’ve got a couple of kits laying around and I bought some D2, some rosewood and some Dymondwood. I’m going to ressurect some old skills. What are you using for handle material? For that matter, what are you using for blades?
Hehehe, well the reason i didn’t use the tape is because I didn’t have any extra. But even if I did, i am not sure that it would stick to the stone too well. I figured the aluminum blanks are cheap and I wanted a permanent mount to those as they are disposable. I can take them both off of the paddle however, and put something else in.
TeroTuf. that’s awesome about you getting back into knife making! I am using 1095 currently and g10/micarta. There is a new handle material out that intrigues me, but I haven’t been able to try any yet, it’s called
The Tero-tuf isn’t available in a lot of colors I see.
I think maybe one of the blocks I sent you was made from Garolite? Garolite is another brand name for G10 - kind of a dark green/brown. Tough stuff. Micarta is different, much more machinable. I’ll do a little digging,.
