These are great guide tools for the beginner, when hand sharpening plane blades. No set-up needed - unlike other guides. Have these in your work shop and with practice you can ditch them. You’ll be sharpening blades like an old pro woodworker.

Bought these as a guide as I've only just started to sharpen my own knives. They work great and helped me get a consistant angle. The one downside is that both the grip and magenet tend to move around if you're not careful. Overall great value!

Useful item with various Angeles to help guide you to sharpening your knives or tools with a handy magnetic base for if your using metal based sharpening blocks on one and a non slip rubber base on the other for traditional sharpening stones

The rubber grip ain't that good to be honest

Bought to guide my angle using a whetstone for the first time so I don't ruin some very nice Japanese chefs knives I was given. Works very well.

Don’t know how I’ve managed without these. Make me things so much easier and gives you that constant angle.

Not as easy to use as i suspected and don't seem to stick very well on my stone.

The magnetic one is weak so it slips on the blade and the rubber none slip one isn't very non slip, if your after this kind of then invest in the guide rails that go on the back of the knife a lot more solid and accurate
