Will diamond rods do the trick?

Hi guys,

One of my S30V users has some flats spots along the edge where the edge has connected something hard. Now the knife is shaving sharp (204 did the job), but these flat spots bother me. Try as I might, I can't get them out with the brown stones.

Will diamond stones do the job and take away my flat spots? Is there a cheaper alternative?

Thanks,

Greg
 
:confused: The knife is shaving sharp, but has flat spots? Are the flat spots shaving sharp too?

Just kidding. The brown rods will take the flat spots out IF you keep at it long enough, but the diamond rods would be faster. Personally, I use a DMT coarse diamond benchstone for reprofiling like that. It took me about 30 minutes on it to remove the chipped spots on my BG-42 Military (I found a finish nail in the side of a rafter I was working on :rolleyes: ). But then, I learned to sharpen freehand before Sal was making Sharpmakers. There are a lot of other tips for reprofiling with the Sharpmaker if you run a search with those keywords.;)
 
For reprofing I lean and clamp with binder clip DMT diamond coarse stone to the flat of brown rod. It is just $20 and works great. I use it dry.
 
I've read some good stories about sandpaper taped on the stones. I'm just concerned that this may scratch the crap out of the blade. I've also looked around for diamond stones in the meantime and they cost more than the sharpmaker. So probably won't end up getting those....

This one is 40 degrees only, it doesn't have the Sharpmaker's 30 degree setting for setting the backbevel. It will work for a while, but if you are like most of us, you will be reprofiling to thin out the edge pretty soon. I don't think I would set the backbevel at 40 degrees on anything more durable than a SAK, certainly not on an S30V Spydie. But if you are happy with that angle, go for it.
 
diamond rods work well, also emery cloth taped to the std rods in about 180 grit work just fine too, they wont scratch anything any easier than a std rod will in my experience, really they work about as well as the diamond rods, if ya are reprofiling and need to remove a lot of metal they really might work a little better with a fairly coarse grit. the cloth works better than std sandpaper, but the paper will work too just makes a mess with all the dust.
 
Offhand, I can't speak of the price difference, but once I got my Edge-Pro, I put away my Spyderco diamond stones.

Once you've set a bevel or corrected a nick with the Edge-Pro, the Sharpmaker is more than adequate for touch-up sharpening.

It may be close to blasphemy to mention the Edge-Pro on the Spyderco forum, but even the inventor of the Edge-Pro will say the Sharpmaker is fine for maintaining an edge. But to set a bevel, or repair serious damage to an edge, the diamond stones can take much longer than the Edge-Pro; at least in my experience.
 
The diamond rods work fine, I have used them to reprofile a few blades. They won't be as fast as an extra coarse DMT stone, but they will be held at the right angle for you. For reference, it took me maybe a 1/2 hour to reprofile a ATS 34 blade from 20-25 degrees per side (it was unevenly ground) to 15 degree per side. That would have taken many, many hours on the brown stones.

I tend to agree, another set of diamond stones collecting dust here.
 
Guys some good advice here. Being a tight a$$, I bought a $0.50 piece of 180 grit paper, used some masking tape and fitted the paper tightly around the brown stones. It took me maybe 5-10 mins to get it fitting nice and snug. I rigged it up and after 5 mins and using 2 sides, there were no more flat spots on the blades and they were shaped just perfectly with no damage to the finish. I then spent maybe 5-10 mins on the brown and whites and she is smooth and just about brand spankin new.

No more need to EVER have a knife with flat spots or a rolled edge! I HAVE seen the light... One should not be afraid to say what the heck and just try stuff.

yep, i agree, if i woulda known that prior to buying diamond rods, well, i wouldnt have bought diamond rods lol, the paper works just fine, try the emory cloth next time.
 
I looked for the emery cloth, but could not find any at the store I visited. I will widen my search a bit to track some down for next time....

Cheers,

Greg
 
I managed to reprofile my ZDP Jess Horn to 7-8 degrees per side with the diamond rods, sharpening flat to the stones. It took about 3 hours, but the stones did the trick, and they still have a lot of bite left in them.
 
for emory cloth try a auto parts store that specializes in paint and painting accesories, an autozone or pep boys wouldnt have it.

a good hardwear store also should have it, for some reason the homedepot in my town does not though.
