When to Use The 15° & 20° Sharpening Angle w/ Tumbler (How-To)

One of the first things many first time customers asked us is when they should use the 15° & 20° sharpening angle with the Tumbler Rolling Knife sharpener so we decided to make a video.

15° sharpening angle
You can use the 15 degree angle for harder blades, for example Damascus knives or blades with a core steel that has a higher hardness degree. These knife edges can be ground to a very fine finish while retaining their stability.

20° sharpening angle
Almost all kitchen knives can be sharpened with the 20 degree angle, as it is a common angle in the kitchen knife industry. You won't go wrong with this one. The knife retains its sharpness for a long time due to the stable cutting edge. The 20° is also suitable for many pocket knives that find their daily use outdoors.

Keep in mind
A 20-degree angle is a more robust angle than the steep 15-degree cutting angle which might offer more precision. Western knives are generally made with a softer variety of steel that is more forgiving to the high-impact style of cutting we do in the West, rendering them too soft to hold a narrower 15-degree angle for very long. Thus, if you change their angle from 20 degrees to 15, they will require more frequent sharpening. Japanese knives usually are made from a harder, more brittle steel that holds a narrower edge for longer and thus can support a 15 degree angle.

Sharpen, restore and repair your knife in minutes with Tumbler.

Mine just arrived today. Can't wait to use it tomorrow. Thanks so much. Great product. Finally I will have sharp knives.

I'm glad I purchased thus sharpener. It's really does keep it simple. The angle was always my struggle because I rarely sharpen knives, with this sharpner I know its always correct.

I wish that these instructions would’ve been included in the packet when I bought my Tumblr. It showed four or five strokes to sharpen a knife not five minutes now I can get my knife really sharp.

Might I suggest having a changeable angle or even just different wedges that you can add to the 20deg magnet in order to reach other angles such as my po ket knives that I like to sharpen to 17 or 18dps, I see this system being very successful just figured I'd offer my $.02 and present it to a wider customer base... Also maybe offer an upgraded stone as an add-on feature for different grits like a 600grit diamond or a 150 for more material removal would be great...

Can you use this on more ‘tactical’ stuff like Tops/Cold Steel knives?

Tumbler, can you use this for straight razors? If not, will you ever create one specifically for them??

New to this, just bought a beautiful nakiri came pre sharpened at 12.5°. Don't have a sharpener. Would 15° have a positive or negative impact?
