CPM MagnaCut Independent Test Results

James Wright of Wood By Wright tested our MagnaCut blades against 27 other plane irons, measuring how sharp each edge stayed over 400 strokes of planing.

Sharp enough to smooth, 2½ times longer.

Most blades lose their keen edge fast, then hang on semi-dull. MagnaCut wears down slowly and steadily.

At 160 strokes, the others are too dull to smooth. MagnaCut is still sharp enough to smooth. Cuts every hair Cuts most hair Too dull for fine smoothing 0 80 160 240 320 400 Plane strokes MagnaCut PM-V11 A2 O1

Edge sharpness measured every 40 strokes, averaged over 3 runs. Independent test by James Wright (Wood By Wright), 2023. See the full data.

“Not only did it outperform all other steels pretty much across the board, it did it very, very obviously.”
