Speaking of gadgets, etc. - Can anyone advise me regarding Martelli ErgoCutter 2000? I've had "carpel tunnel" issues at times (not too much lately thankfully). Somewhere I read these rotary cutters were better for wrists, etc. Considering purchasing one, but I am wondering a couple things: First, do they have a safety guard (cannot tell in photos) and secondly, how did the transition go for folks who use this equipment. (oh, and 45mm or 60mm?) I would appreciate your advise folks. Thanks for any help.
