I pretty much only use double guillotine cutters. I really like Cuban Crafter's Perfect Cutter and Xicar's Multi-tool Cigar Scissors.
Bruno:Great everyday carry! It compliments your clever monicker on B&B @The Count of Merkur Cristo!
Unfortunately, I don't think Wenger makes multi-tools anymore. It sometimes comes up on ebay, I think.
I bought mine about 15 years ago when Wenger competed with Victorinox. I don't know if Victorinox offers a similar tool but it may be worth checking into.
Hope that helps.
