Yes, if you're not set up for it. MagnaCut's edge life comes from very hard vanadium and niobium carbides, which ordinary aluminum oxide stones struggle with. Diamond plates, diamond lapping film or CBN work best. Each sharpening takes a little longer, but you'll do it far less often.

I make blades in small production runs. If yours is on the shelf, it ships right away. If not, you can reserve one from the next run; your payment holds your place, and each blade's page shows the expected ship time before you order.

If your plane is listed above, the link takes you to the blade made for it. Not sure, or don't see your plane? Email info@lakeerietoolworks.com and I'll help you figure it out.

How long a blade stays sharp comes down to two things working together:

• Wear resistance: how slowly the edge is rubbed away by abrasion. It’s commonly measured by machine (the CATRA test), cutting card stock loaded with abrasive. That measures abrasion only, not the impact and prying forces of real planing.
• Toughness: how well the edge resists chipping, from the microchipping that dulls a keen edge long before it wears away to the larger chips knots, very hard woods and end grain can cause.

A brittle steel can score well in the abrasion test and still lose its keen edge quickly in hardwood or end grain. MagnaCut has high wear resistance and high toughness, so it holds a keen edge in real work.

• vs. PM-V11: PM-V11 scores well on abrasion tests, slightly higher than MagnaCut, and it sharpens on conventional abrasives. MagnaCut is significantly tougher, though. In real planing that toughness keeps the edge from microchipping, so MagnaCut stays keen longer, especially in dense hardwoods and end grain.
• vs. A2: MagnaCut is both more wear resistant and tougher. One customer reported my blade lasting about 3 times longer than his A2 iron.
• vs. O1: O1 is easy to sharpen, but MagnaCut is significantly more wear resistant and tougher.
• vs. AEB-L: AEB-L is tough, takes a keen edge and sharpens faster than MagnaCut (though not as fast as O1), but its low wear resistance means sharpening significantly more often. MagnaCut holds its edge much longer.
• vs. M2: M2 is a high-speed steel (it resists softening at high temperatures, which suits it to lathe turning tools) with good abrasion resistance and reasonable toughness. MagnaCut is both tougher and more abrasion resistant, so it holds a keener edge longer.

Every blade is double tempered and cryogenically treated to Rockwell C 62. MagnaCut is also highly corrosion resistant, so a keen edge stays keen in a humid shop or between uses. If it doesn't stay sharper, longer than the blade you have now, the Edge Promise gets you a full refund.

That's covered by the Edge Promise: if your blade doesn't stay sharper, longer than the one it replaced, send it back within a year for a full refund. Return shipping is included for US customers.
