The SystiMatic 37102 50T blade cuts every bit as smooth as my WWII.
Both blades are very sharp, hold up well and have sufficient carbide to
allow for several sharpenings. In fact the SystiMatic has less runout on
the plate than the Forrest. (SM 0.001 - FWW 0.0015) However, both blades
produce identical finishes when ripping, the SM produces a slightly better
finish when cross cutting hardwoods.
IMHO (well not really so humble!) both blades are of equal quality.
