Ive only tried it once, Its very sturdy and easy to set up, and a great way to develop your skills holding a consistent angle while habd sharpening. Overall, I'm impressed with the build quality.

What a great tool. I can keep the angle at all times without thinking. Makes sharpening super fast.

an amazing tool, especially for beginners, sharpened 4 knives so far and they consistently ended up razor sharp. 10/10

Only negative would be the writing of the angle degrees is very poorly applied. Like almost illegible in a few places and looks like it will wear off easily.

I wish it worked better with longer knives but really happy with how it worked for normal sized chef knives.

Works great.

Really like the creative ideas such as the small angle indicator and on board tool. Very robust can’t believe it is a printed part. Really glad they’re creative and motivated people out there.

Well designed
The clamp is a bit weak, but it will do on bigger blades

The best tool for people who are learning how to use stones to sharping.

Well-designed, well-manufactured. Excellent attention paid to human factors engineering. This thing does just what it needs to do. Does it well. Very happy to have it

The concept is well thought out, and the quality of the product is amazing! The finish and tolerances are spot on.
I had thought that it would be a good thing to consider injection moulding with increasing demand and sales, but seeing the thing in real life has put that thought to shame; it's some of the highest quality 3D printing I've seen!

Yeah this thing is amazing

Very happy with this. Start learning the freehand sharpening. Help me keep the consistent angle. Thank you.

Great idea. It works well.

Very effective and easy to use. Gives a nice sharp edge

This handy little guy has seen heavy use. Amazing for someone that does not have a very steady hand
