James K. ★★★★★

The C4 sub-micron carbide is noticeably more rigid than the brazed cutters I've used before, and it held an edge through a full run of hard maple without any chipping. Installed easily and the profile came out perfectly clean on the first pass.

Claire ★★★★★

I needed a replacement set for my backcutter and these carbide knives seated perfectly with no play. The edge held up noticeably longer than the original steel blades.

Harper ★★★★★

The C4 carbide is noticeably denser than the braze-tipped knives I’ve used before, and the fit on the Insert-Pro was dead-on with no slop. Put them through a full day of oak and they’re still cutting clean, no chipping at the edges.
