I have several different rotary cutter bu different manufacturers. I use them all at one time or another but my go to is my Olfa 45 mm, also.
The main reason I wanted to post on here is that I recently did something I wish I had done about 4 yrs. ago. I have 4 grandbabies whom I love more than I can ever explain. I bought a plastic storage container @ JAF that you can put a lock on. So I gathered up all my rotary cutters & put them in the box & locked it up. I have always had a fear that one of my DGC would some how (I always keep them put up in a high place) get ahold of one of them. 2 of my DGB live close & are at our home frequently.
So I thought I would share this idea with others who may have children or GC, who could potentially get ahold of them. I would be crushed if any of mine got hurt because of my carelessness. BETTER SAFE THAN SORRY!!!
