Beginner question - blade rub on multi-blade traditionals?

[isko]

It seems that I can't avoid getting blade rub marks on my recently purchased multi blade traditionals. It's particularly bad on knives that have 2 blades on one spring. I've attached two pics (sorry for the quality) of a case stockman I've had for about 2 months, and already there's a lot of blade rub marks on it. Is this normal? I don't feel like I see a lot of pictures on here with this type of marking on it. About 15 years ago I had a Camillus stockman which I used for years, and I don't remember seeing any marks like this, but that knife had 3 springs instead of two. Is that the difference?

Well, I have two Case Stockman, til now. Everyon of them has blade rub. At the same places on the blade as yours. So I think, that´s normal. I wouldn´t worry about that. Case does a hand-finishing on their knives (I think).

Kind regards

More or less usual on Stockman CASE knives, not on their Humpback pattern though. Frequent on Whittlers as well, very likely on most production patterns needing crinking ,looks worse on stainless knives rather than carbon with patina. Don't mind it too much provided it doesn't compromise opening/smoothness.

Hi,

In a production knife it's often hard to get the krink just right on every knife. Krink refers to the bends put in the blades to get them to clear when closed when you have more blades than springs. Like on your Case Stockman. This is why 3 spingers like your old Camillus or Bucks don't have this problem most of the time. Each blade is straight.

There can also be a bit of flex in each blade as you open them that can cause rubbing to.

I mostly don't worry about it very much. It's often just a part of the beast and seldom affects usage.

Blade rub is fairly common. I think some of it is due to the user pushing the blade against another when opening it. Some of it is a lack of fine tuning and sometimes it's a mistake. I had to send back a stockman that slipped through QC -- it had a sheepfoot that was supposed to be krinked but wasn't. If you post a well shot with the blades closed (see photo below), a problem would be easier to spot.

The knife on the far left has some rub between the spey and sheepfoot blades. This is a problem with fine tuning and not uncommon in my opinion. The other two knives don't rub. I didn't take a photo of the knife that I had to send back.

edit:
Here's the same knife (right) shown next to another knife of the same pattern that was better finely tuned (left).

I carry stockmans during the week, I've never paid attention to blade rub, but after taking a look. My 2000 Case stockman has some blade rub between the apey and sheepfoot blades. You really can't see the rub marks since the sheepfoot is so scratched. My craftsman (shrade) from '69 is perfect, no blade rub.
Both of these are users so I don't pay much attention ....

I'm adding a new GEC stockman to my rotation soon and it's just plain perfect. No rub at all.

Note: Didn't mean to single out Case, I just picked up a Russlock. I'm a fan.

This knife is well made IMO and it has blade rub. Not when the blades are just sitting there or when you let the blades snap shut, but when you open the secondary blades. Pushing over with the nail nick can cause them to rub the main blade. It doesn't bother me on this knife. If you lift straight up with the nail nick they will not rub. The main blade doesn't have enough flex to rub the secondary blades during opening.

Fairly common occurance on production stockman and congress patterns. Unless the blade edge actually is hitting something, it doesn't bother me.

I noticed it on my case stockman as well. It never affected use though. I say use it and if it starts becoming a problem, send it in to warranty. I think it's pretty common.

As Corey already added, as long as the blade is not hitting another blade or a liner, it doesn´t bother me. That happened to my Case Peanut with the pen blade. But nevertheless; the clip blade still works, though it´s not centered. (It´s a reason to train my sharping skills )

I've got it on my small Case Stockman too, but not on my Trapper. If it really bothers you, you might check out the Buck 301. Three springs, straight blades; mine has no rub marks at all and I've had it for better than ten years now.
