I got this blade in poor conditions for relatively low and i have some doubts .
It has a bad/unfinished polish and some rust splash with spider scratches on the edge.Shape is good and is very sharp(almost razor).Its likely been in military usage,its mumei but has on the tang like 4 straight horizontal lines that could be 22,to keep track at an armory? or was the blade nº22 of a swordsmith order?
My doubts are: it was forged like this or it was shortened? Does anyone who recoginze the shape guess the age(shinto?)?
Is worth of polish?Thanks
