Maintaining gear is important and so I've decided to learn how to sharpen knives. I bought a couple of sharpening kits and a cheap beater knife to practice on.
This is a Smith's brand sharpening set. There are three different stones from coarse, medium to fine. The bottom contains an oil to help the process. Basically the process starts on the coarsest stone then moves to progressively finer stones when an apex had been raised on the current stone. Well, that's the theory. In practise you'd likely only use the coarse stone to change the blade profile, fix a chip or a broken tip.
This set is for quick touch-up jobs to hone an edge. The kit includes medium grit rods too.
And, the rods store inside the base making this a great kit for the vehicle.
This is the cheapo beater knife. It's stainless steel with a true Scandi grind. That means the blade is straight at the top before coming to a V part-way down. Scandi is short for Scandinavia - which is the origin of this grind. Scandi grinds are meant to have quite good strength while still having enough of an edge for fine tasks.
Stainless steel isn't the easiest to sharpen, but a true Scandi, that is one without a secondary bevel, is pretty simple: angle the knife on the stone along the Scandi bevel and get grinding. The downside is Scandi can take some time to sharpen because you have to remove a lot of material. I'll learn on a true Scandi before I attempt secondary bevels and then eventually convex grinds.
I think I did okay. Most of the factory machining marks are gone, the rolled tip fixed and the knife does a better job at cutting paper. We can tell where along the blade edge needs more attention if the knife tears at the paper instead of cutting it cleanly. Much better!
Not perfect, but progress I guess.
I'll blunt the beater knife on a brick and then go practise again. I'm told that sharpening is mostly about muscle memory and consistent angles, so I expect to take some time to learn.
Now for a comparison of value knives. The beater knife looks similar to a very famous budget knife brand. But, to be fair, knives generally come in styles and companies will do their own version with most differences in the materials and manufacturing process and only small differences in the form
From top to bottom: Morakniv Companion Carbon Steel, Morakniv Companion Stainless steel and, the Beater knife in Stainless steel.
The most obvious differences are that the beater knife has the longest blade, the fattest handle and the biggest finger guard. Oh, and the cheapest price tag: beater knife is one third the price of the Moras. But, the blade comes out of the handle at a much flatter angle on the beater knife, so a larger finger guard is a good idea to stop the hand accidentally moving on the blade. This is less of a problem on the Moras because of the handle angle so they don't really need such a big finger guard. Also, beater is advertised as a bait knife so it's likely the user's hands would get wet and slippery - so again, the bigger finger guard makes sense.
The Mora stainless has the shallowest Scandi and both Mora companions are not true Scandies because they have a secondary V bevel near the edge.
Bigger differences are viewable from the top. The beater has the thinnest blade with Mora stainless in the middle and the Mora Carbon having the thickest blade. The beater's handle is fatter around to give a good trip.
As a bait knife, a thinner blade in true Scandi with a decent depth shoulder gives a rust resistant design suitable for bait cutting when you don't want to use your fancy filleting knife. The handle should give decent grip in the wet. But, because of the blade profile and probable cheapness of the material - I wouldn't trust the knife for much more than light duty.
The Mora's are more of an outdoor knife. The thicker blade and secondary V bevel give a more robust edge for general camp tasks.
Anyway, I'll practise some more. I need a leather belt or strop next. The guy at the shop suggested I recycle old belts from the thrift store: a belt not suitable for wearing can have new life as a strop to get that shaving sharp edge.
Out.
