I recently treated myself to a Koil Kutter and it's great for cutting the larger jump rings but when I'm trying to cut .8mm ss wire with an ID of 2.5mm it's cutting a groove in the jump ring opposite the cut.

I was wondering if anyone else has this problem or is the cut-out bit on the white guard a bit too high? If I measure the amount of blade that actually goes through the groove in the plate it's just over 3mm, does this sound right?
