Kerf-and-Wedge Board Flattening
Relieving a twisted board with a deep center kerf, clamping it flat, and gluing in a wedge — flattening with a fraction of the jointer's material loss.
Running one blade for every cut is why beginners fight tear-out, burn marks, and a blade that seems permanently dull. Tooth count is the main variable: fewer teeth to rip solid stock, more teeth for plywood and fine crosscuts.

Most beginning woodworkers run whatever blade came on the saw for every cut — ripping 8/4 hardwood, crosscutting trim, breaking down plywood — and then blame the saw when the plywood edge shreds, the maple burns, and the blade feels dull after a month. The blade isn't defective. It's being asked to do three different jobs, and tooth count is what decides which job a blade is good at.
For cutting solid wood along the grain. Fewer teeth means each tooth takes a bigger bite, and the deep gullets between them clear sawdust fast — which is what lets thick or dense stock feed smoothly instead of burning. If you rip a lot of hardwood, this blade pays for itself fastest.
The compromise blade that lives on most saws, and reasonably so: acceptable rips, acceptable crosscuts, no blade changes. If you only own one good blade, make it this — but know that both extremes (thick rips, veneered plywood) are where it falls short.
For crosscuts that show, and above all for plywood and other veneered sheet goods, where a coarse blade lifts and shreds the face veneer. More teeth means each tooth takes a smaller bite, so the surface comes out clean — at the cost of slower feed and faster heat buildup if you push it through thick solid stock. The creator keeps an 80-tooth thin-kerf blade for plywood, which is a standard choice.
The pattern behind all three: big bites for bulk material along the grain, small bites for delicate faces. And thin-kerf versions of any of these are worth considering on a lower-powered saw — less material removed per cut means less motor to remove it.
