Good UToob vid Adrian and thanks for posting. Many folk in the West, inc moi, like using them for various reasons one of which
may be that they assume, for one reason or another, that they're 'superior'. After much deliberation I've come to the conclusion that they're not superior, just different and it's maybe that which is part of the allure.
When I was in Japan a few months ago for 'cherry blossom' season, I discovered this
place as I was after a
Tasai chisel(s) with the very pleasant swirly patterned steel blades, so I enquired of the English speaking boss.
'No so sorry, we don't stock them as our professional chippies who tried them told me quite adamantly they're no use for site/shop work' and he directed me to the ones they do stock, which were very ordinary white paper steel blades but superbly forged and he then showed me why.
It appears that these very fancy, very expensive chisels etc are made for the Western market where buyers think they're getting something special when what they're paying for is the blacksmith's artistry at the forge to produce a very pretty tool - Rob
