When I get a chance I will post a pick...I love my Classic SD too and wanted the option of a bottle opener. I clip my keys together with a stainless steel spring clip (something like a carabiner) and it is an excellent bottle opener. I don't think it costs anymore than $2 (US). Also, it has about a 200lbs working load limit!
They are in the rope and chain section of stores like Lowe's and Home Depot. I seriously recommend this option because it is not only minimalist but multi-function, all the while eliminating redundancy!!!
