Re-Profiling my RC-5

I am a little confused. Why can you not scandi grind something that is saber ground. Basically it is just taking the primary down and getting rid of the secondary. Doesn't seem like that big of a deal.... Also for the question of keeping a convex knife in good shape it is very easy. Just get a full set of 220,400,1000 and 2000 grit wet/dry sandpaper from your local auto parts place and a mousepad. For most uses all you will need is the 2000 to touch it up and run it on the strop and it is good to go. For some reason the other day just to get a quick edge back on my mini-canadian i ran it over my sharpmaker about 10 passes on the brown corner and 10 on the white. Got it back to being a very good edge and was out the door quickly. I would not recommend doing this every time but it put a great edge on when i had not alot of time.

I don't have a 5 but I would bet that the secondary bevel is under 12.5 degrees per side which is the minimum scandi grind for O1. So if you were going to grind the secondary bevel down so they meet, you would have serious edge problems.
 
Just sharpen it well on an EZ Lap stone and be done with it.

It is, as noted, for bashing/ chopping your way into or out of something.

Are you trying to use the knife as a general purpose combat knife, bashing bar, shovel and axe replacement and framing hammer? The RC5 is supposed to do this.

If you want to dice garlic cloves or perform surgery, the RC-6 is a better choice. If you want to skin animals and such, get a -3 and keep it with your -5
 
I still think it's a damn good idea and it may be worth the 30 dollars to have someone do it right... one day when I'm rich and can afford 2 RC5's I'll have it done.
 
The RC5 can be a hairsplitter-it can take just as sharp an edge as any of the RATs. I don't see what's so hard, a 20 degree angle on a .25 inch thick blade and maintaining a 20 degree angle on a 1/8th inch thick blade should be the same....
 
i suggest taking it to a knife maker to get it done.

what will you do about the coating?

PS i took my RC 5 on a sort hike today. i chopped a batton from a long piece of dead wood and then battoend some wood for fun. the knife works well enough but its not for tomatoes though.

It can split a hair no doubt. It's passing the thickness of the blade through whatever you're cutting that's the issue, not the edge itself. Which is why I don't think convexing will solve anything. It's still a quarter inch of blade to pass through. the fatter wedge has to push the material further apart to get through it. Good for splitting something hard, "bad" for cutting anything that isn't gonna pop apart. The edge itself is really irrelevant to any kind of slicing discussion.
 
but if you take the grind all the way to the edge of the saber, I think it would turn this monster into a real splitter/chopper.
 
I convexed just the edge on mine and it cuts like a laser. I have used it to slice onions and tomatoes with no problems at all. With use you learn how to make it work pretty well for such tasks.

However it ill never be as good a slicer as say a Fiddleback woodsman etc.
