Great source for Tersa knives

Great/reliable source for Tersa knives.

I’ve used Tresa M+ knives for many years and feel that they deliver a clean and smooth cut for both the jointer and planer . The only drawback is that they dull quickly with certain dense tropical woods that I’ve been forced to use over time. Obviously purchasing the carbide versions would handle the task nicely , but at a steep cost increase , sigh.

Wish I'd found them sooner

Were great to deal with including international shipping. Received them quicker than when I order here in Australia. Saved myself 30% even with the exchange rate. M+ and Carbide.

Definitely the place to buy your tersa knives from.
