> 3 daySo far so good, had no problem to mortise through oak. Big question is how long will it stay sharp for? Good product for the buck.

> 3 dayInitially it was great but if felt like it got dull pretty quickly. Overall it’s still pretty sharp, but the tip is what’s used the most is dull. If they can add some kind of coating just on the tip it will greatly benefit its life. But I also have a WhiteSide brand tool and I feel like it lasts longer.

> 3 dayI was very impressed with the quality of the cuts and the outstanding fit of the parts. Im making 6x6 pergola posts using 2x6 #2 lumber. By machining one surface flat on the planer and then laying the flat side down on the CNC table, I get perfect dadoes and rabbets which perfectly interlock.
