Knives are priced per blade.
Please contact us for sizes that are not on the list.
We can custom cut to any length.


Tersa™ Carbide planer knives are the perfect match for daily and extended use with ​all hardwoods, exotic woods and material with glue lines. Although the carbide steel is more brittle than high speed steel, if used on clean wood, it typically lasts 8-10 times as long.

For softwoods, HSS blades are recommended. Not sure which Tersa knife to use? See our recommended knife for each wood here.

Cuts as good or better than steel. I was skeptical, but have been using the carbide for years now with no regrets

Simply uncomparable

I have tried various types of cutter heads in wood surfacing machinery. They all have their place. But as a primarily hand craft furniture studio tersa gets me where I want to be with a machined finish that is quickly and easily polished with hand planes. When sharp out of the box, the Tersa Carbide will finely finish even some of the most highly figured Curly Koa I work with. The material is so precious ( and insanely expensive at over $125 per BFT) that waste from inferior finishing devices is unacceptable and painfully expensive. has for over a decade provided me with the fastest, cheapest, and most enjoyable service. Their cutting of the knives is clean and burr free. The packaging and speed of processing the order is second to none. I receive my orders usually in less than a week. The cost is typically 20 to 40% less than any other source in the world for a US based consumer. The sales staff is always promptly responsive, pleasant, and helpful to work with. I think of them as part of my business network , same as my wood suppliers and and other essential services my business uses.
I have hopefully brought more folks into the fold. It's one of the few companies that I can easily endorse after years of positive experience with them. Tersa knives are amazing but make them truly exceptional.

A very satisfied customer
Fantastic service, great knives

I was in a bind—suddenly dull blades after working with teak for the first time and Felder telling me I could not get replacements until July. Then I found TersaKives. Overnight delivery and carbide knives!!! I will always get my blades from them in the future. Thank you.

Thank you and I will definitely return for more
