Best Knife Grinder For Beginners

Grinding is an art, and not everyone is perfect in this as it takes lots of practice and time to master. But apart from practice & time it also needs some tools like belt grinder or bench grinder which gives you the best grinding result.

A knife grinder needs to be robust enough to grind bevels and grind the general outlines of knives, hopefully without going through millions of belts or grinding wheels and hopefully in a reasonably short period of time. Not just knife blades, they are used to grind handles, woods, pins, pretty much every other material in the shop.

You have to consider lots of points while buying the best knife grinder, such as the belt size, motor, speed, noise, vibration, dust collection, and much more.

Buying guide for the best knife grinder for beginners

Belt size:

The grinders are called by the belt size they use. The most common type of belt size used is 2x72 inches, and almost every professional prefers to use a 2x72 inches belt over any other belt. Their reason behind this is that the smaller belts wear out very quickly and they also don't grinder as efficiently as a 2x72 inches belt does.

You can use any belt size you want but keep in mind if you want excellent performance, then your first priority should be a 2x72 inches belt, of course, if your budget allows.

Variable Speed:

Variable speed is an important factor you should consider while buying the best knife grinder for beginners. Most knife grinders do not have variable speed option, which makes it quite tough for the beginners to grind something on it because most beginners don't know that how much pressure they need to apply on their knife while sharpening it for the first time, which sometimes makes ruins their knife blade.

That's why if your knife grinder has a variable speed option, you can slow down the speed according to your need and then increase it again after being comfortable.

Frame & Vibration:

Any time when you work with high-speed rotating tools made for removing metals, you have to deal with something called chatter that's the tendency of workpieces to vibrate against the cutting or grinding surfaces of the device.

The vibration makes it harder to work accurately. The more massive and the more rigid the frame of your grinder, the better it will operate. When you're evaluating the overall quality of the knife grinder, remember that a good frame is a heavy frame.

Easy To Use:

The best knife-making grinder always comes with features that are easily accessible use any user, especially beginners. A tracking wheel plays the most important role that makes a belt sander easy to use. This tracking wheel doesn't allow the belt to fall off the machine.

Can we use a bench grinder for knife making?
