OT Need a good knife sharpener

The regular blade on my Leatherman (simply awesome!) is starting to get a little dull. I'd like to sharpen it back to it's original razor sharpness. Anyone know of a good sharpener that will restore that razor edge? I know I'll kill it with a bench grinder.

There used to be a guy that would drive around in a truck and would sharpen just about anything you could imagine, but he hasn't been around in the last few years. [img]images/graemlins/frown.gif[/img]

Re: OT Need a good knife sharpener

1. Cut a wooden disk (3/4" wide) to fit your bench grinder.
2. Make a trough 3/4" wide by the circumfance of the disk made in step 1.
3. Pour fine carborundum particles into the trough.
4. Spread them evenly along the trough.
5. Apply White caprenters evenly to the circumfance of the disk.
6. Let it get a little "tacky."
7. Roll the disk made in step 1 along the trough to imbed the carborundum into the glue.
8. Set aside the disk and let it dry.
9. Mount the disk on the grinder after it's good and dry.
10. Use this disk to sharpen you blades.
11. You can keep your fingers on the blade as no heat builds up to burn your fingers or blue the blade.
12. It works great!
13. I've been using one for about 15 years now... and love it.
14. Just keep the carborundum on that disk!
15. It's makes best edge I've ever been able to put on a blade. [img]images/graemlins/grin.gif[/img]
16. As a test... I shave with it!

Here's some "paper" wheel shaprening disks that are very similar to what I use:

Re: OT Need a good knife sharpener

You never fail to amaze, LEVE. That's quite an idea, though I'm pretty ham-fisted when it comes to grinding things. I can handle lawnmower blades and the like, but more precise edges give me fits. I'll have to try this out on an old pen knife first, just so I don't botch up the Leatherman.

So you shave with a straight razor? Now that's a man's man! [img]images/graemlins/smile.gif[/img]

Just in case I can't handle it this way, are there any commercial sharpeners that anyone might reccomend?

Re: OT Need a good knife sharpener

1. Shave with a straigh razor?
2. Nope, I used to when I was young.
3 How I learned to hate that razor....
4. Now I just use my PST Leatherman! [img]images/graemlins/tongue.gif[/img]
5. As an aside, if you muck up the blade... you can get new ones from Leatherman...

Re: OT Need a good knife sharpener

Hey Mike, I'm the type of guy who always has a multi tool or a knife with me at all times. I always keep mine razor sharp. The easist and best way that I have found is the Spyderco Knife sharpner. It cost about 40 to 50 bucks but it is well worth it. It is really easy to use, and you won't screw up the blade temper. Many sporting goods stores carry it. Or even gun stores.

Re: OT Need a good knife sharpener

This is what my dad taught me to use

IMHO there's not a better knife sharpener in the world. [img]images/graemlins/grin.gif[/img]
I done a Google search for Tri-Hone if you're interested. Be for warned they aren't for everybody, they require a lot of patience and practice. [img]images/graemlins/crazy.gif[/img]

Re: OT Need a good knife sharpener

I've seen all those "miracle" knife sharpeners out there - even the motorized ones, and the angled ones, etc.

I've also spoken to many professionals on the matter. They all say the same thing. Of every product on the market right now, the absolute best is spit and a sharpening stone. No other sharpening technique will give you as true of a blade. Unfortunately, it takes tons of practice and is an easy way to screw a blade up. I'm still far from perfecting the science.

Re: OT Need a good knife sharpener

I sharpen all my cutlery for work ,ect by hand . I only use diamond hones and fine grade whetstones , never anything mechanical . I may try to make one of those carb wheels, good idea . I used some years ago for lawn mower blades, they do work very well and don't build up heat .

Re: OT Need a good knife sharpener

the best thing i have used was a lapadairy mach. for grinding rocks. it had three diffrent grades of grit on three diffrent belts all in a line an on the end was a peice of rawhide that we put rouge on. the belts also had a water tank that driped water to keep the heat down.
the other thing i use is a old sharping wheel, its old,
the wheel is 20 inches 2.5 wide runs backwards at 40 rpm it runs in a tray of water i have made blades out of old files they relly work nice.
i like leves idea the best except for the heat DONT GET A BLADE TO HOT.

DUKE


I have stones, dia. hones. angle stones, oil stone, wet stones,
they all work you just have to know how to use them an some take a lot of time to know to use them.
