Hello. Got a Byrd robin a few weeks ago for a spare edc. I have noticed that there are indentations near the base of the blade from the knife opening and closing. Like a couple rainbow shaped scratches at the base of the blade. Seems like its rubbing on something causing these scratches. I would have thought the steel would be harder than anything on the inside of the knife. Do I have a lemon? If I buy another will I likely be okay? Thanks
