Ok, I bought a Japanese 15" 10TPI Shark pull saw and did some crosscut playing around on a green 4"x4". I cannot get a straight cut? I then get out my off the shelf Craftsman 14" 8TPI and I was able to cut clean and straight? The Japanese blade is real thin compared to the Craftsman and that saw just wants to bear off the line? What am I doing wrong ?? or does it just take some getting use to? Help again in cold & wet Ohio.
