Watch Case Opener

The Watch Case Opener, or Case-Back knife, is designed for the horology industry. The special blade is used for opening watches with a pressure fit (snap-back) case. Both Swiss Army Knife manufacturers have produced these special purpose blades for a long time. Most knives made with them are advertising premiums made for various watch makers and jewelers. Normally these are found on small Alox scaled knives, it is also found on the largest collector's versions of the SAK.

Victorinox

The early Victorinox versions are smaller, have a sharper edge, and come to more of a point.close up of the Victorinox version of a watch case opener blade

Wenger

The Wenger version tends to be larger, more rounded and with a more dull edge. Over the years though, Wenger has made a number of different blade styles, as watchcases have evolved and changed in size. Wenger also makes a fixed-blade case-back opener blade, that does not fold into the handle of the knife. This model was still in production in 2012.close up of the Wenger version of a watch case opener blade
