Edge Pro Sharpening Tips, Mistakes, and Lessons Learned

Yeah, I've used 1/2" wide stones on recurves. First, use a flattening stone to bevel/round the corners of your 1/2" stones.

Any chance you can elaborate on this ? Trying to figure out how I would do this. Don’t want to attempt on an expensive custom
 
I just rounded the corners off mine so they would sharpen in the middle of the stone instead of just the 2 edges
 
fwiw - Congress Tools sells stones used by machinists and die makers.

The Moldmaster stones are hard silicon carbide for very reasonable prices. They work well on the Edge Pro when diamonds are not necessary.

CT offers quite a few sizes including round shapes for a recurve.

I have the moldmaster 1×6 stones mounted to edgepro blanks works really well for badly damage edges or for a major reprofiling or thinning. The only downside is they do shed a lot. This keeps fresh cutting abrasive always at the ready. But if you have a lot of knives to do it will get a little messy. Still worth it when you need it

Sharpened this Rosecraft Barlow.

Used my TS Prof and profiled with Venev Ursa stones that are .6" wide. I wanted to shoot for as high polish as I could get, so after profiling, I switched to Edge Pro Matrix stones that are 1" wide. That was a mistake, because the thinner Venev stone had happily gone over a very small recurve at the heel, but the wider Matrix stones started jumping over the spot. I didn't fully realize what had happened until I reached my 2.3k Matrix stone and the difference in polish was revealed. Lucky, the edge was well apexed from the Venev stone, so I finished on the Matrix 4k, then tried to save the polish with a .5" wide glass stone with 6k polishing tape on it and then 1um gunny juice on .5" mounted basswood. So the edge has an uneven polish. it is cloudy towards the heel, but the edge is very keen and I managed to get the tip needle sharp.

I am a big believer in using narrow stones navigate uneven factory grinds in small blades. I would have stuck to the narrow Venevs, but I only have up to 800 grit on them and I was fixated on high polish. I have some narrow CBN stones coming that I am hoping become my main stones for anything under 4"

Using narrow stones on uneven factory edges might be the best tip for fixed angle sharpening that I've run across. Fixing "off angle" areas with 6x1 stones can take some time and my require manipulating (twisting) the stone. Both open the door for screw ups. I recently used a .6" Venev stone in 160 grit on my K03 to fix an especially jacked up factory edge and it was way easier and much quicker. On factory edges, using a narrow stone as the "first stone" may become SOP for me. Thank you, Dutch87!
