Use A Binder Clip To Maintain Your Knife Sharpening Angle

If you’re the type who wants to sharpen knives yourself with water stones, you’ll quickly learn that a proper angle is key. Luckily, the beautifully versatile binder clip is perfect for maintaining the right balance while sharpening.

This actually came up in our comments before, but reader Jon tipped us to a video on showcasing how a quarter-inch binder clip gives you just the right angle for your standard chef’s knife on a whetstone. Clip the binder to the non-sharp side, and you can use it as your guide while running the blade down your watered stone. The video can’t be embedded and usually features a pre-roll ad, but it’s a good demonstration to watch before going ahead.

Sharpening Knives With a Whetstone []


  • Except that the whetstone will grind the clip as well so not only do you get plastic fragments in your slurry, the clip actually deforms over time and you lose that angle. Bottom line – if you are going to sharpen knives like this, learn to judge and hold the angle manually.

  • I agree with Kato. The binder clip would ruin your stone. If your stone has a curve in it, its broken, throw it out. Stones need to be flat.

    Different types of stone grits make for different ‘speeds’ of grinding too. I would have laughed if this article recommended a 6000 grit stone for sharpening as an example. Generally, the lower the number, the more coarse it is and will take away steel fast. Like a 100 grit stone would be used for fixing damaged blades. From there 400 to 1000 grit stones are for polishing. Then after than you can run your blade over a Steel. To make it ‘scary sharp’ you need a leather strop. The device used by barbers to sharpen their cut throat razors.

    Sharpening a knife is amazingly complex and technical.

    Just get a angle guide. Angle guides are really convenient. I bought a Gatco system. Works really nice. It also has different grit level stones too. The kit I got also had a stone to sharpen serrated blades. – This being Australia, we prolly has disclaimer laws, so, I am in no way associated with Knives Australia other than being a customer in the past.
