I used mine once or twice. Tried giving it away but no one wanted it.

We've used them at the store for about 8 years. We still have 2 that we've used the whole time. You don't have to push down as hard, so if you're cutting all day long, it's easier on your shoulder. The grippers come loose sometimes, but we just clean them with water and a paper towel and they stick again just fine.

They are in the way for smaller accurate cutting, but for cutting yardage, it's great.

Something I've always done is to lay my hand flat on the ruler with my pinkie and ring finger off of the ruler. Ring finger holds the side of the ruler. I also have the glue dots on the bottom of my rulers. I also formed a handle in the middle of the ruler with the gray duct tape. I probably should get new ones, some ar 30-40 years old. lol

I have an O'lipfa 22' Safety Shield on my 6x24" ruler. It has an adhesive tape that really stays on and it works great just don't place it too close to the edge so that the knob of the cutter hits it. Had a customer come in and complain that her shield was always in the way.. I have had mine shield on that ruler for over 15 years. I don't need a shield on my small rulers I place Omigrid "invisiGrip" and they don't slide. We tried those grippers when I worked at the quilt store but the ladies cutting did not like them and that is when I placed the Safety Shield on the ruler.

I had the handle and found it cumbersome to use. I also thought it interfered with reading the ruler. Mine was donated to Goodwill.

Are you talking about the press on stuff that is see thru? If so, then yes and it works fine. I have also used some of the vinyl that I bought off the roll from Wal-mart (yes, the stuff you use to cover a table or can use for inserts or whatever) and it seemed to work as well. Some of my rulers/templates have it on and some don't. Which reminds me I should put it on the others.

I was teaching a 'safety with cutting tools' class and cut off the whole side of my index finger (ironic!). Pretty bad cut, to the bone and requiring 6 months in a cage with therapy (at least it happened at work). While it happened because I was not paying attention and was thinking about the next thing, it still scared me to the point that I purchased one of the suction grippers. Funny thing is that I required my students use it, but I don't use it. I think about it, but then don't use it. I do, however, focus on what I am doing and move my hand further from the edge!!!!!

OK, I'm confused. Do you just place the Slidelock rulers over your regular ruler? The Slidelocks don't look like they have any markings on them.

stabalizing your ruler
 

I use shelf lining rubber matting cut slightly smaller that the ruler I am using and it holds nicely to the fabric.

I use the clear "Nexcare" adhesive first aid tape on the undersides of my rulers. Cheap, readily available and see-thru. The tape is textured, so it grips the fabric and keeps it from sliding. I have put it on all my rulers and don't have a problem.

Adhesive backed sandpaper also works well, but is not see-thru.

I had a suction-cup handle and it went into the "give away" pile. Not worth the money.
