I like the Olfa with the automatic retractable blade. However, I notice my girl friend has an olfa cutter without the automatic retractable blade....you push the button up to cover the blade with this one. Because my girlfriend is ampidexterous (sp) she is able to cut, using this cutter with either hand. Makes cutting go much faster. I love to cut with her cause I do the right hand cuts and she does the left hand cuts.

I love , love Martelli cutters. I own 5-6 of them.

Kai cutters engage and retract with pressure or the release of that pressure - no fiddly slides or buttons to push and no accidentally leaving an open blade in the wrong place. I have 8 different ones.

HANDS DOWN the Martelli ergonomic rotary cutters!!! They are the absolute best out there..If you sign up for their Redline Direct sales, you can frequently find these @ 50% off their retail price.

I recently treated myself to a Martelli cutter and 10 blades during their 50% off sale. As someone above mentioned, the cutter tends to veer off to the right at the end of a long cut. I have no idea why, have never had that happen with my other cutters. I'm disappointed in the blades. I'm on the second one (don't use it that often) and again there's a "bad spot" on the blade and I have to keep going over the areas where it hits.

I have several cutters and just checked the one I most often reach for. It has no identification, the only thing it says is "made in Korea". I've had it for years and don't remember where I got it. It's the most comfortable and dependable to use (and I have good luck with the Harbor Freight blades).

I have and use exclusively the one you have to squeeze to engage the blade. No accidental cuts yet!! Some close calls with the types you have to push the little thingy to open, I don't always remember to dis-engage, with the squeeze on, it's automatic.

I really thought that I would have a problem keeping the cover on mine but didn't want to spend so much money since I wasn't sure how successful I would actually be at quilting. So I got a mid priced Fisharks one with a button cover and it actually worked out really well. I love the cutter and because it is the kind that I started with it was easy to always remember to cover the blade. Plus I quilt on my dining room table and sometimes have my stuff laying out when the step kids come and had to warn them very sternly about the cutter.

I'm with Jeanne. I tried the Fiskars version, but for some reason this one is much better. I found the Martelli to be awkward when I've tried it at shows. I definitely prefer the retractable types for safety reasons. You still need to be careful, but being retractable does reduce the risks.

I have the new supposedly ergonomic Fiskars with the squeeze handle to expose the blade. It absolutely kills my hand and I cannot use it.

I highly recommend martilli cutters and their customer support. Their design helps with avoiding hand fatigue!
