I have three crkt minimalist. I carry one every day as a back up to my other self defense mechanisms.
The little blades are quite handy, but, I would like to have a reverse edge on one. The bowie model I have. I don't have any electronic tools for the task. But, I think it would be too much. I went and purchased 400- 800 grit wetordry sandpaper...but, I'm nervous. Can anyone just give me a quick pointer? I know it's a cheap knife. And I have some other high dollar blades I wouldn't dare taking sand paper to them. I figure, I either learn by fire, or keep dreaming...I'm ready to burn.

Btw, I did a search. I can't seem to Get a result using mobile...so the mods know, I at least tried! Also, if this needs to move, please do so...
Thanks!
 
Much like this. The main edge with the curve, but also one on top

I think OP is referencing a secondary edge along spine of blade (pic's not showing for me either).

I would highly suggest reviewing the laws related to knives, fixed blades, and weapons for the jurisdictions where you live and travel. Where I live, knives with multiple sharpened edges are specifically referenced as being illegal to posses and/or own (depending on specific municipality codes).

Additionally, making a statement to a LEO that a carry knife is a "defensive" tool, arguably gives the LEO sufficient evidence to consider the knife a "weapon" vs. a simple tool (named a pocketknife). Then by default laws relates to furlative carry of a weapon come front and center, along with locations where "weapons" can not be possessed (but yet knives are not specifically excluded). I believe it better to be informed, as related to my regional laws, that at the mercy if LEO's. In the big city near where I live, folks are routinely arrested for possession of simple tools simply because of what they said to a LEO, or how they were in possession of the tool.

I don't mean to preach, just food for thought ...

Also, it's would be my assumption that most experienced knife/tool folks would have no issues putting their blades to sandpaper. Many actually prefer the diversity it offers in both sharpening and finishing of edges & surfaces. It can be back with soft surfaces to produce or sharpen convex edges, or back with hard substrate to work flat bevels.

Ok, now I see what you mean. While carrying may be illegal, I'd still grind down a minimalist for a fun project. I'm not sure how long it would take by hand sand paper, so give it a go and post some progress for us.
 
@Spey & @bludgeon, I'm in south Georgia. No legal issues here with doing what I Want. Thanks for the advice!

Not sure of the pics Not showing...odd, they show on this side
 
If you're trying to put an edge on the back side of the blade, it can definitely be done. That's normally called a false edge, as it's normally not sharpened for cutting. It's just brought to an edge for easier penetration when pushing the blade through something point first.

I've done this a long time ago on a very thick blade. Sandpaper wouldn't have begun to touch the job. I spent probably between 5 and 8 hours on mine using a file. A LOT of metal was removed in the process. If I were to do it with sandpaper by hand for some crazy reason, I'd go as low as practically possible. At least 120 grit, if not 80 or even 60. With a belt sander you could probably do it reasonably quickly, but you'd need to be careful about heat when removing that much material from a blade.

Good luck!

Brian.
