I was told when i bought my HH-3 5.5 double swivel shears 5 years aho that they would have a life time warranty... about a year ago i started having issues with my shears doing scissor over comb. They started snagging and pinching the hair in between the blades alomg with the fact my swivel falls off constantly ( i shouldnt have to tighten that daily)... I called Hattori Hanzo about 6 months ago and told them what my issue was. They in return told me that my shears would probably need sharpened and said they wouldnt do anything for me about looking at what my issue was as if they could do nothing about it. So I sent my shears in, and lo and behold when I got them back they still weren't working right. I gave up after this, i had called the company and talked to someone there and talked to a representative who sells them locally to me. I had originally wanted to order some thinning shears from them but they don't seem to want to help me with my issue on the shears i already have... So i will never buy from them again. I will say they were amazing and they have no catch points, so when you flip them into your hand they don't scratch you anywhere and they aren't very comfortable... I just don't think that I would spend another $900-1200 on them again for the same result.
