I start with a 50 grit then 120 then 400 grit pre heat treat on 154cm. AEB-L post heat treat I do 50,120, Trizact A65 then A45 and hand sand. Damascus I do A 30 pre etch. On 154cm after heat treat I do 120, trizact progression again.
I sand with an 80 grit belt then use an edger for the corners. I dampen the leather then rub with saddle soap to smooth , next a hard plastic piece to rub to smooth.
Then you are advertising in the wrong market and you are using a sheath maker who your need to do a search for a less expensive maker. You can make all kind of excuses about why not to do it.
Evidentually you don't know how to price your knives or the values of nice knives. A Knowledgeable maker passes costs onto the buyer and both come out ahead.
Sean it is more than just the small wheel. There is a flat plattern leading up to the small wheel so you can lay the flat of the blade on to it then move it to grind the curve on the bolster.
I think he is referring to a small wheel holder. Uncle Al has a grinder with a small wheel that the guys who make integral knives use to finish the transition from blade to bolster.
