Thanks for the link to the video. It looked to me as if the person in the video had trouble opening some of the knives, but not the Kasumi. I'd really like to know exact length. My Take has a 93 mm handle, but it is hard to measure, since the shapes are not regular. I'd have trouble with this while wearing gloves.
I hope to get some user comment on the Kasumi and the Gentleman knife... and lengths.
