Replacement Blade Pair for our Thicknessing Gauge. Made from Swedish Spring Steel, 050" (1.27mm) thick, hardened to RC 52.
The Thicknessing Gauge acts as a scraper, and so both blades cut with a burr. The bevel on the blade is 45°. To sharpen, first hone the bevel lightly on 150 grit sandpaper or a medium stone. Remove the burr raised by honing, then re-establish the burr with a carbide burnisher.

Blades should be kept lightly oiled or waxed to prevent rust. We recommend Jojoba Oil, a plant based oil product that is non-toxic, odor-free and easy to use. Also, in our shop, we use a fine abrasive handblock to remove any light surface oxide from tool bodies and blades. Jojoba Oil and abrasive handblocks are available from us.
