I wanted to remove the carbide cutter from my PSI pen genie so I could hone it. But could not find the her wrench any where. I have misplaced it before and found it in short order...not this time. I called PSI to see if I could order a new one. After getting my name and checking a few things the young lady I talked to said she would send me a new one at no charge. I think that really good customer service.
