Hi Jurgen/Wookie-
My combat-grade Steel Heart-E had what can be best described as nearly invisible "drip marks" that ran nearly 2/3 the length of the blade. It was more noticeable on one side than the other. It almost looked as if the "drips" were laying beneath the black crinkle finish.
What was I to do? Naturally, I placed a phone call out to Jerry & Team!

The good news is that we determined the mark was just a characteristic of that particular blade coating. Same as a scar in the skin on a leather jacket or a variation in the color/shade of a natural wool sweater.
The even
better news is that we decided I should just use the knife as planned. If it still bothered me a few months later, I could return it to Wauseon for a complimentary re-coating!
Well, I've reasonably used (not abused) the knife for several months. The coating shows a tiny amount of wear and I've slightly smoothed the crinkle finish by
gently wiping with a Scotchbrite pad on occasion. You know what? The mark has practically disappeared and I don't even think about it. No way this thing is leaving my side for no good reason!
FREE ADVICE: Keep your blade clean, oiled, and sheathed when not in use. If out in the field, dunk it under some clean water and wipe it on your trousers. Put some oil on it when you get home a few weeks later.
Given the average co$t of these knives, I think we all tend to get a little bit "hyper" about them at first, I know I did! You really grow to love the knife when it becomes a true "user" and you're not agonizing over it and worrying about what silly little tasks may dull the blade.
Welcome to the Busse page on BladeForums and make sure to
ENJOY your Steel Heart-E, my friend.
