Carry this one for two years now (and a Huntsman for many years before I got this one) and I absolutely love this thing! Fits perfectly in my front pocket attached to the Victorinox belt chain. I use this one many times a day and felt helpless like a baby the one time I forgot it at home and needed it. Recently decided to show it a little love and change its scales to my favorite color and combine them with green accessories (toothpick, tweezers and lanyard).
Yes. Yes you can!
I recently modified mine. Used a heat gun to expand the plastic and then a spudger to carefully lever the plastics off of their mounts.
Used a (padded) clamp to close the new scales back on.
