Ogee 替換刀，用於 Insert-Pro 延伸榫頭

The C4 carbide is holding up beautifully after a full day of shaping maple, still razor sharp where my old brazed cutters would have dulled by now. Fits the tenon head perfectly with no wobble, and the finish on the workpieces is noticeably cleaner.

I had to cut some notoriously hard walnut and these knives held their edge far longer than the brazed ones I used to use, which saved me a ton of downtime. The sub-micron carbide really does make a difference in how clean the cut stays, even after heavy use.

The C4 carbide is noticeably tougher than the brazed cutters I’ve used before, and the edge held up through a full run of hard maple without any chipping. It seated perfectly on the insert-pro head with no fiddling, and the cut quality came out glass-smooth right out of the box.
