Hi
yes.. wootz is a funny creature.... if you leave it to air harden.. then you have a potential for pearlite ... and you'd let the carbides do the cutting.. (pending on the type of carbides......as there are many kinds with various hardnesses..... eg fe carbide, V, Cr, Tungsten ??? ) or you can oil quench it.... and get martensite .....which will be much like our modern blades...... and you can temper this down for a more springy tough steel ..... or leave it hard, chippy, and not very tough at all..... or somewheres inbetween which is where you'd have some edge retention and toughness... aswell ... you don't need to clay coat the back to get differential hardening... here is a little bowie i did.... that had no clay .... and a canolla oil full quench... -- as you can see..... only the edge was hardened... as the steel i used was W1 (a shallow hardening steel much like the old carbon steels ) http://i43.photobucket.com/albums/e3...kel/total1.jpg http://i43.photobucket.com/albums/e3...ownoverall.jpg http://i43.photobucket.com/albums/e3...kel/tipup1.jpg fun stuff Greg -- |
