I have been reading up on different replacement/upgrade stones for an Edge Pro Apex and Congress Tool stones came up several times.

I emailed them for recommendations and will share their thoughts when I get them, but I was hoping folks who have used them could give me their impressions of the different kinds of stones that Congress offers for an Edge Pro.

I will be sharpening knives from O1 and 1095 to 154CM and VG-10 and up to 3V, CTS-XHP and S90V.

I've read that Moldmaster and EDM stones are good, but does anyone else have any recommendations? Also what grits are recommended?

Thanks for the help!
 
I have the Molmasters and they work great. They cut very fast and wear pretty dang slowly from what I've seen so far. They are cheap, too!
 
The Moldmaster and EDM stones work great. I have a Flex in 600 grit that Congress recommended to me. It never seems to wear out. I use Ruby in 80 and 120 grit for re profile work. You can get the aluminum bar stock to mount the stones at the big box home center stores.
 
Thanks for the replies. It's good to know that several lines of their products have been used effectively with the Edge Pro.
 
Here's the email response I got from Congress:

Unfortunately we do not have any expertise in the Knife Sharpening trade. Our stones are manufactured for industrial applications. The knife sharpeners have stumbled upon our stones and have found them to be quote useful. We have received a lot of positive feedback from the Knife Sharpening trade for our Moldmaster and also RUBY stones. Additionally, for a final stone finish, our FLEX-600 stone is very popular.

Looks like I'll be making an order soon.

I know this is a six year old thread, but does anybody know how the stones are mounted to aluminum bar stock?

Thanks

I use 3M Super 77 spray as well but be careful how much you on or may run into problems.

I just use a mist coat on the stone and the blank and wait until they are dry to the touch and if you go by what the back of the can say's for drying time it's pretty close to how fast it should dry,if however it's taking 15 minute's and the glue is still wet then you used way to much and if the glue feels really slippery if you rub the stone or blank with your finger that's good sign you have used to much glue.

Try testing the glue on scrap peace's of aluminum or steel that you have laying around on stuff like L bracket's and the straight peaces you can get at the hardware store.

If you want to remove the Contact Cement just use Lighter Fluid or you can also buy Contact Cement Remover as well from a lot of hardware stores,I have used those product's to remove stones from blanks to recycle old blanks from stones such as Jende Industries because they use 3M Super 77 as well.

There is a stone supplier that uses 3M 300 LSE tape. Although I have only recently got the gritalon stones and have no issues, Wade has been using the stones for some time now and may be able to provide more feedback.
 
I would have to say the Gritalon stones are better then the Congress Tools Silicon Carbide stones.

I found with the Congress stones they seem to wear faster and on 2 of the grit's when I was sharpening a Kitchen Aid knife the 2 stones worn so fast they looked like washboards with massive ripples.

I'd have to give the nod to the Gritalons for sure,the Congress stones are good as well and it was only 2 grits that done that to me and I threw them out and I can't recall what grits they were.

The Kitchen Aid knives I've worked on are soft stainless. Use a harder-composition aluminum oxide stone, and save the (apparently) softer silicon carbide stones for harder steel.
 
I just them because that's what I had out at the time and didn't feel like soaking more stones,I agree with what your saying I just couldn't be bothered to that day.
