How to fix slightly damaged edge

[patio87]

If you look at the image below on the belly of the blade edge you will see a area where the edge is pushed in from me accidentally striking the edge of something. How can I fix this? Can I fix this through normal sharpening?

Looks like a small roll. This is something a steel might fix. Try lightly steeling it a few times. Dont overdo it.

Its not really something i generally reccomend. Asides from that the damage looks minor , even a 1k stone should be able to get it up to snuff. If your not comfortable or equipped to do it yourself then you can send it out to one of us.


This would be a good opportunity to learn to sharpen though.

That looks pretty minor, so far as I can see in the pic. Should be easy to fix via normal sharpening. What are you using for that, and what steel is the blade made with? Depending on what you're using, a slightly coarser abrasive might work more effectively to repair the damaged portion, or at least speed it up a bit.

I'll look into this. And yes I have been wanting to learn sharpening. I have a couple very cheapo knives I have been practicing on. I currently only have a fine grit stone but I will probably run to the hardware store and get a set.

The knife is a Kershaw blur blem, it's either Sandvik 14C28N or 440a.

A basic hardware store stone should work, as would many other options. The steel shouldn't be a big problem, either way. Could even 'strop' the edge on some medium-grit wet/dry sandpaper over a hard backing (glass, or used over your existing stone); I often fix 'dings' in edges like this, and some 220-600 grit should take care of it pretty fast. Your factory edge looks like it'll more closely approximate the 220, or lower. I'd not try coarser grit (below 220), as the heavy scratches left would be more difficult & tedious to clean up, especially while still learning sharpening. With sandpaper, it's much easier to 'practice' on higher (finer) grits first, to get the feel for it, and it'll minimize the blemishes left by mistakes in technique (like scratches too high on the blade). Same would generally be true with stones as well.

I went to the store and picked up one of the Norton Fine/Coarse stones. I noticed that on the fine side it feels like there are a few spots that are rougher then the rest. Also the edge on one part seem a little bit raised. Am I supposed to do something to fix this or is it normal?

That sounds familiar; I have the same stone, and it came in pretty much the same condition (using it today, in fact). Easiest way to take the 'bumps' off it would be to lightly scrub the stone on some concrete, perhaps using some water with that. The bumps will chip off pretty easily, as these stones shed grit pretty readily. I've done the same using another coarse & inexpensive stone of mine (a 'tile rubbing' stone, also picked up at the same store). I wouldn't worry too much if the edges of the stone are somewhat raised, though if they're extreme, they could also be rubbed down a bit on the concrete.

Could also use a cheap blade to break in the stone, scrubbing aggressively with it, as if re-bevelling. As I mentioned, the stone will shed grit easily, and this will knock a lot of the rough spots out.
