FRN Grittiness

Postby loamy47 » Thu May 09, 2019 11:46 pm

Every time I take my FRN Dragonfly Salt to work, it ends up getting a bunch of grit in the pivot that leads me to take it to bits almost every day to clean it. It isn't so bad as to significantly worsen the action or anything, it's just more of an annoyance that doesn't happen with my PM2 that I recently got or any other knife I've had. When I clean it, all I do is take the pivot screw out, wipe off the blade pivot area, pivot, and the area of the handle that the blade comes into contact with, throw on a very small amount of a dry lubricant, and put it back together. Am I doing something wrong/does anyone have any tips on keeping the grit out?

The blade length may be the culprit here. Shorter blades get the handle closer to the work.

I don't feel you are doing anything wrong bud. But seeing as how it's h1 steel and you use a dry lube, I would just hold the lock open, open the blade halfway and rinse it out.

I use a Tasman Salt HB that hasn’t seen a drop of oil in the two plus years I’ve owned it. I use it to clean fish and I’ve dropped it in the surf open and had wave action bury it more than once ... it gets gritty.

We have plenty of water pressure at our taps and I just flush it out at the sink (when I remember) and it always flushes clean. :)

Thanks guys. Just tried flushing it out and it worked perfectly.

With my Dragonfly I only end up cutting the odd strap or cutting some plastic wrap on a pallet of building material, but I work with a lot of concrete so the particles of cement dust end up getting into my pocket one way or another and that's where most of the grittiness comes from.

Honestly i can't think of a way to remedy this if even dry lubricant won't keep grit out of the pivot.
Have you taken the PM2 to work with you?
At that point than the only difference I'd see would involve phosphor bronze washers

My dragonfly h1 hasn't had this,but my salt 2 does seem gritty, or at least less smooth. I just assumed it was the lack if washers.

I don't think you're doing anything wrong. I would see what happens if you get a longer knife. Also, no need to take it apart. Either just flush the pivot with some hot water, or some oil (if you want, it's not needed for an FRN Salt with no liners). Salt's are resilient as heck and don't need anything really. Amazing knives.

i’ve had this problem with my df2 salt. i want to say “all the time,” but really i just dealt with it for a long time and finally cleaned it out recently. it’s feeling better now, but there’s still a little bit of grit after a couple more days of carry. i only carry the df2 at work, and only as a back up serrated edge, so it doesn’t see much use. i’m guessing it’s more of a pocket lint issue. at any rate, it doesn’t bother me that much, and when i can’t take it anymore, it’s a really easy problem to fix, especially for a salt version.

A couple things I do to my linerless FRN knives is take out the blade and polish the tang (H1 polishes so easily) and then take some fine sandpaper and knock down all the sharp edges along the inner edge of the handle to make sure there aren't any hard edges to rub the blade during motion. Then I put a little bearing grease on the pivot and they stay silky smooth. I don't get into much gritty/dusty environments but grease in pivots seem to create a barrier to keep crud at away from the pivot. I could also see it holding the crud in place if you do work around sand/dust/gritty environments so I would try just polishing the tang and put it together dry and see how that works.

I'd actually been considering this. Sounds like I'll be doing this today. No work until tomorrow, but I'll let you know how it works.

I had to take apart my spyderhawk yesterday because I went to the beach Saturday. Couldn't rinse the sand out. Sometimes I can get it with some compressed air but this time it wasn't working. Usually I hold the lockbar open and rinse it with water and spray air in it. I passed a towel through the handle slot. Put a few drops of tuf glide after. Working like new.

This is why I strongly prefer screw construction, especially on a Salt model. Hopefully the Manix LW Salt is screw construction if it ever comes out.
