I actually wore out my last 12" paper trimmer, cutting paper until the blade was too dull to be sharpened anymore! I decided that any tool that gets this much use in my studio needs to be the best quality and this Xacto Trimmer is just that! The combination of light weight, the laser light guide, the ergonomically agreeable handle, the locking mechanism for the guillotine blade and the non-skid feet make it a true winner in my opinion. Best of all, it cuts straight and square! Sadly, not every trimmer does that. It is not an inexpensive trimmer, but it's worth every penny!
