I love mine, and how utilitarian it is.
Obviously, first and foremost it can be used as a guillotine cutter.
Though for a while now instead I've been opting to only close the blade around the cap enough to pierce the wrapper. I will then carefully rotate the cigar, until the cap is delicately severed, and pops right off. This allows me to avoid any kind of pressure damage, and the results are much neater than the average guillotine nip.
Let's talk about some potential functions of the knife itself. Cutting pesky plastic wrappers or difficult bands are a given.
I've found it particularly useful in situations where I have had to step away from my smoke for a while, and when returned it needs a full relight. You can use the razor sharp blade tip to carefully "trim" away the ash and scraggly bits, resulting in a more clean and even surface area for a relight.
If you're a fan of punches or V-cuts, this won't serve as a replacement. But I think it's an excellent tool to carry, for many other reasons.
