My first new hinderer I just got last week was looking so forward to getting one for the longest. I’ve had a zt0566 0550 0562 0562cf 0560 but got my first hinderer m390 spanto no choil with blue anodizing. To my surprise, straight out of the box it wouldn’t slice through newspaper. I thought eh printer paper no problem. I had trouble with that. I had to push cut it. So I took my strop and hit it a few times on each side. Still nothing. The edge is polished and looks decent but it isn’t sharp. Any thoughts or opinions. This is my first actual hinderer and I get the spanto is a thick hunk of metal but my 0550 and when I had my 0560 in elmax it would get a razor edge. I feel really let down and am considering returning to dlt.
