I have a 6" fillet knife by Melvin, and bought his sharpening system.
Melvin has put a lot of time and effort into developing a very good heat treat for 440V.
I sent him some ironwood, and my fillet came out great.
Melvin is a bit strange and distant to deal with on the phone, you have to kind of pump him for information. He sent me a very mild and inoffensive religious message with the shipment, I thought inappropriate, but also inoffensive.
But don't let that stop you, his work is excellent and is worth seeking out if you like his standard designs (he isn't much on taking any custom orders, say, with your sketch).
