really nice knife set, you want to take lots o photo's of what youve done. advertise on ebay.com (usa site, or ebay.de, german site) if u sell on commision basis i.e. i think you will do alright.
commision based knives i america can be $2-3000.00 dollars
a1 is one of the best steels to work with, hardened to r59. the only others i would consider:-
440c nice to polish finish, can resharpen in the feild
D2 very hard to work, nice polish, can be very hard to sharpen, but holds edge well.
all above can be bought as blanks on ebay
the only other peice of advice would be to convex grind the blade (less resistance in use)
it has been a pleasure reading this thread, you are an excellant knifemaker with individual well thought out designs
thanks mike (knife collector)
