Review on Ulmia Frame Replacement Blade 700Mm by Dave Russell

I bought this blade for a DIY panel saw designed by Paul Sellers. It's great: the teeth pierce evenly, the rake angle isn't too aggressive, the rake angle seems to be around 10 degrees, and the set is heavy, which favors rough work like trimming branches or bucking logs or coarse wood. However, the blade must be sharpened after unpacking. 6 inch thin file seems correct.
