Most bushcraft style knives will I suspect be in o1, D2 or similar rather than stainless steel so good luck
Will keep my eyes open on my travels , I always try and track down the camping, bushcraft , shooting shops wherever I go in the country with work
Another thought have you had a look at some local makers , try Shing in Derbyshire or there are many others do a google search on handmade bushcraft knives
Another idea would be to have a look at the country shows, I picked up a nice one at the Midland Game fair last September
Good luck with your search
