Fallkniven F1 3G deformation problem

Hi there everybody,
I have a F1 3G which has been used for a couple of weeks to do some light works (nothing special, just split some soft and dead wood, made some tinder, prepared some food and cut some ropes), but incredibly the blade deformed in some points.
The marks are very little, but still, it deformed! I don't think they are chips, but surely this seemed strange for me, as I didn't abuse of the knife and for what I know the F1 3G blade is very very hard (62 HRC), but it is also supposed to be very very tough at the same time, so this fact quite annoys me...
the knife is still very very sharp (not hair shaving...).

Question is: what is now the best way to properly restore the blade and remove the deformations? Do I need to send it to Fallkniven or can I do it myself?
I've already ordered a Fallkniven DC4 sharpening stone and some 3M Wetordry Sand papers (from 200 to 2000 grit) and they are on their way to my place.

thanks guys!
 
I've fixed my nicks and chips with sandpaper & mousepad. DC shapening things are way too rough for my taste, leaves ugly finish on the blade.
 
Your going to need to post pics for accurate help.

If the edge is still sharp (and you say it is) it's probably not actually deformed, maybe the way the light is reflecting off the edge is just throwing you off.
 
I agree that some pictures would be helpful.

I find most knives will easily micro chip, or roll a bit on the factory edge. this has been true on my VG10 and 3G blades as well.

After they have been sharpened two or three times and you get into some "virgin" steel, the edge is much tougher.

Not sure if this is what you are experiencing, but it kind of sounds like it may be.

yes, the deforms are on the edge.

here are some pics... these are the best I could do...
if someone needs them bigger (actual size), please tell me

What he said,
 
Ouch that looks like chipping to me. I could be wrong though.

My F1 didn't do that the first time I took it out. Try some gentle sandpaper strokes to see if that helps.
 
Send the pics to Fallkniven. Explain the situation and ask them if that's normal. I'm thinking bad heat treat, but Peter should respond pretty quickly.

I'd definitely let Fallkniven know, send them the pictures, and ask for their thoughts on it.
 
I did some stropping with 400 grit, then 800 and finally 2000 to polish the blade.
even if I am not that good/expert in sharpening, I managed to take away the major deformations/chips after just a couple of strokes...
there is still one minuscule chip on the edge...

I'm going to write Fallkniven anyway, but now my question is:
if it was really a chip, could I have been able to remove it in such little time and with such little effort? or was just a roll?
 
Did it ever get grounded during use? Either way that should not happen. I would believe that Fallkniven would cover this. Moreover that seems to be a defective blade. 3G as hard as it is shouldnt chip like that based on your described use.
 
I would use it and sharpen it a couple times before making a determination.

what do you mean by "grounded"? (sorry I'm Italian... :) I don't understand some tech words)

I am planning to use it some more time now that it is "less chipped", and if it will chip/deform just once more, I'll ask Fallkniven if there's anything wrong with it...

problem is... even if they (Fallkniven) say that this particular knife went out bad, they can't replace it, 'cause it's no longer produced :( ...
 
AF has the idea ! It could be grinding damage .I've seen that before especially the tip. Resharpen and you might be able to remove the grinding damage.

Probably "Have you hit the ground/sand with the knife?", hitting a rock (or other hard item) in the ground is a great way to chip and dent blades. It's probably just a problem of the factory edge as has been mentioned, it should be able to handle more after some good sharpening by yourself.

The chip in the last picture is a bit deeper than what I might expect to see, but overall this looks pretty "normal" by my experience on a factory edge.

After you sharpen the knife a few times, I'm confident this will no longer happen unless you accidentally strike the edge on a rock or something similar.

Here is a pic of a similar micro chip on my Fallkniven Cowry X after batoning on the factory edge.

It sharpened out fairly easily with a belt sander (Cowry X is very abrasion resistant).

I have sharpened it a couple times now and have no further chipping.

thanks guys for the answers!

no I never grounded it or hit it on a rock or something... I'll definately try to use it some more time.

just one more question: now the whole blade is quite scratched by the sand paper... to polish it by hand, I have got a 2000 grit paper... how do I have to work with it? Circular movements or linear?
 
That doesn't look like anything except normal wear & tear. Rope for instance can contain grit or other abrasives, as can wood. Just sharpen the sucker. SHEESH!
