Why are planer knives sold as matched sets?
A planer doesn't care how sharp one knife is; it cares that every knife in the head cuts the same. Knives ground as a set, to the same height and the same edge,
are what keep a cutterhead balanced and a board surface free of the ripple that mismatched knives leave behind. That's how every set leaves our shop: ground flat, matched, and ready to install without shimming guesswork.
Skarpaz T1 high-speed steel holds its edge through production runs of hardwood and abrasive stock, and when it does go dull, the set comes back here: reground flat and re-matched on the same equipment, so the second service is as good as the first.
