"I was impressed from the start—this cutter arrived quickly and the packaging was beautiful. The moment I held it, I noticed the weight—it feels solid and well-crafted. The engraved details are stunning. The mechanism opens smoothly, and when I made my first cut, it was flawless—no damage to the cigar at all. This is easily a 10/10 product for me!"

I recommend

Color: Gray

I really like it small enough for everyday carry cuts clean and has a punch my only problem is I like bigger gauage cigars but this handles average 60 ring easy.
