Sharpening serrated blades

[Durp13579]

If this is in the wrong place, apologies.

I recently bought a knife for diving. When it arrived, I found that all the edges were dull. I sharpened the main blade, but not the serrated or the gut hook. On the serrations, the teeth are on both sides of the blade. I was wondering if I could use a mini crock stick to sharpen the serrations. On the gut hook, I know I need a file, but I don't have one, so I will buy one in the future. In the mean time, is the crock stick okay?

Thanks.

If it's small enough to fit into the serrations, I don't see why not.

Tapered round diamond hone, IIRC EZ-Lap makes one.

Correction, DMT makes a tapered pocket diamond hone that opens like a butterfly knife, Lansky makes a serrated stone for their jig and why not go with the originator of the modern serration and the tool to keep it sharp, the Spyderco Sharpmaker.

Okay, I'll try it.

You can also just wrap wet/dry sandpaper around a metal or wooden rod of the appropriate diameter for either the serrations or the gut hook and it will sharpen it just as well. Use wd-40 as a lubricant with the sandpaper and it will keep it from clogging, sharpen faster, and make it last a whole lot longer. The serrations are a bit of a pain because they should be done one at a time but they stay sharp a lot longer also.

I've been a diver for 40 years and most of the older dive knives are made of very soft steel that does not keep an edge well.
That did not matter back in the day when my dive knife was only used as an abalone iron.
Then I had an incident where my wife got caught in an overhanging snagged fishing net at 140 ft. I got her out, but I started carrying a good line cutter afterwards. My choice for a line cutter is a pair of EMT shears. They cut pretty much anything. Some of the newer dive knives take a somewhat better edge, but still are not very useful underwater. If you need a sharp edge underwater other than the EMT shears, I can recommend the Spyderco Salt knives - they stay sharp. They use some kind of nitrogen formula to keep things stainless, yet they are pretty hard.
