Talking ghetto style knife sharpening

As I say in this video, I use cheap knives. They don't sharpen easy and I don't usually care all that much. I mainly use them to brain fish... but then I would enjoy having a sharpish edge once in a while.

I tried many things and found this quick solution :

Re: ghetto style knife sharpening


Thanks. I'd be nervous and wouldn't want to do that on one of my nicer knives, but i am looking forward to trying on one of my knives I don't really care about.

Thanks for posting. Raining and nasty here in Fl today this weekend. So going to be a weekend of playing around in the garage. Teaching my son how to change spark plugs and oil today in truck, so will take Dremel to knife as well!

Re: ghetto style knife sharpening

Now, why didn't I think of THAT!

Of course, some of the best ideas are the more simple ones. Thanks for posting, Rene! C'est bien fait.

Re: ghetto style knife sharpening

I use a similar knife made by Dexter. Looks similar, but the handle is bright yellow and there is a bigger tang to keep your hand from slipping up onto the blade area. It goes for around $12. The shop I buy from sells a slightly smaller blue handle version that looks exactly like yours. I'm going to guess its the same stainless as your knife. I've never had trouble sharpening and getting a nice edge with conventional stones. Sometimes I'll use a wet stone grinding wheel which makes the process a lot faster and easier.

The one thing to watch out for on those types of knives is the corrosion that typically occurs where the blade is embedded in the handle. The plastic does not create a watertight fit against the steel therefore saltwater gets forced in under pressure when you dive down. Rinsing the knife in freshwater won't get it out. You may go to brain a fish one day and the blade will break off right there. With the amount of corrosion on your knife, and the inexpensive cost of a new one, I'd keep that one on land and buy a new one. Smear a good silicone sealant at the blade to handle interface and you can prevent the corrosion from even starting on the new knife.
