Hi. Went to Eugene, Oregon knife show last weekend. I'm fortunate to live only 60 miles away. Brought a wak with me, which has kanji (?) on the left-hand side of tang. Two persons read the markings as Sukehiro, and said the blade was from the 1700-1800s. One of them, a nihonjin, said it was gemei (fake). The third person said the blade was from the 1930s, based on the fuller or blood groove. The condition of the wak is poor, with rust. Plus, it's missing the habaki. I'm tempted to sand-blast the blade, and parkerize it, but I know that's sacrilege. I live in sort of a bad neighbourhood, and a local guy brought the blade to my door, looking for $25 gas money, which I gave him. I figure the blade is worth about $150 (?). Can someone translate the markings for me? Thanks.
