How to reprofile a knife blade

Since there are numerous techniques of maintaining knife blades, we can’t still associate them with the right one. For this reason, here I will describe the best way to reprofile a knife blade. 

Step 1: Gather some grit stones

Can you fix a broken knife tip?

First of all, take a dull knife and spend quite a bit of time on the edge Pro. Just take a low grit stone and try to bring the edge back. Then draw them with some sharpie on both sides. Afterwards, make your whole spot colored by putting on a grinding wheel. 

When you are done, take off the majority of your knife’s metal on a grinding wheel. Then finish refining and cutting a new bevel on a belt sander. And then take a file for the edge row which will make the edge consistent along the whole length. 

Step 2: Work with the edge Pro stones

Next jump in with your edge Pro stones and finish the knife. So now your edge is drawn, the next step is to remove the majority of your material with a bench grinder. For now, replace your coarse wheel with a wire brush. And if you see, your wire brush will get a lot of use, especially with the yard tools and other stuff that come in. Moreover, some high carbon knives get the rust off pretty quick.

Well, a bench grinder is kind of risky to use because if you heat up the steel too much, it may change the temper of the steel and effectively ruin the steel. So that is why you need to go real slow and a low-pressure will pass. 

Step 3: Take the knife’s metal off

Anyway, take your knife’s metal off slowly so that the hot metal does not touch you. At the same time, cut a bevel to center your knife’s edge between either face of the blade. Now, take off material on any side to keep your knife’s edge in the center.

Make sure each bevel is the same size. Then take your restored tip to the belt sander and just take a couple passes down. As a result, you can cut the fresh bevel effortlessly.

Step 4: Use stones on the back of edge

However, you can’t go heating up your steel. Otherwise, you are gonna ruin it. For now, reprofile your blade at 21 degrees and be ready with a burr and a couple of nicks. Using these alternatives, you have to work on your edge back and get your nicks out.

Without a sander it would take a long time sawing away with a stone. Well, a sander, i.e. one inch by 30 inch belt made by grizzly can be a good object. On the other hand, a 240 grit belt can also make your task smoother. 

Step 5: Swap your belt

A flat platen will allow you to set your knife up and have more control over the angle. Besides, it is opposed to cutting on a round wheel. For this reason, you are to swap your belt out to put on a dust collection.

Right now, you have got a bevel and the edge is the same as bevel. Well, I feel like a monstrosity would do a real nice job at reprofiling a machete. And by using stones, you can save a lot of time in reprofiling your knife.

Step 6: Pull some strokes

Then pull some strokes off the blade coming back your angle on the belt sander. Make the angle constant across the whole bevel. And remember not to work the tip too much on your belt sander as it can heat up a lot.

So this will be a nice way to get that edge right at the tip. Still, you will need a little work to make a pass down.

In your file card, you will see one side is a little wire brush and that is for heavier coarser files. On the flipping side, there will be some stiff nylon bristles which don’t get gummed up easily. Now, you have to cut a chamfer on each side of files to make them fit nicely in the edge Pro. 

Step 7: Make an ultimate sharpness

Nonetheless, you can just put your knife back on a bench grinder and read the chamfer. Well, a burr built and its building on both sides can be helpful to build it in one pass with the stone.

After you have brought the edge back on a belt sander, step through your diamond matrix tones from edge Pro. Next, finish working on your knife using an eleven hundred grit diamond matrix stone. Thus, your knife will become sharper than it has ever been.
