Modified mini Victorinox Knife for Snap-On Case Backs
This modified mini Victorinox
Knife
Has become one of my favorite openers for small Ladies Quartz Watches. My
watch tutor had the idea to modify this knife when we encountered some
difficult to open watch cases after a flea market excursion.
What makes the difference to the
Meikosha "MKS" opener (with similar properties) is that it's grip is thinner
and flatter. Therefore one can not apply the high force possible with the MKS
opener. Which can be an advantage, because one cannot accidentally drive the
opener into the watch case when slipping. When some of my wife's Quartz watches
(that I had not opened before) needed battery replacement, I remembered having
this opener and it came very handy.
Opening snap-on watch cases is probably something very personal and every one
has his trick tools. I am adding these pictures here, because this little knife
has helped me to avoid opening marks on very small watch cases with very thin
opening groves.
Of course this little knife has a regular blade too. I had taken a bit off the
edge with a water stone. Thus despite it's really small size, the knife offers 2
openers that might come handy if you are dealing with really small watch cases,
e.g. those found in so called "bracelet watches".

The detail view of the nail file tip
This is the other side of the same blade. Originally it
was a screw driver tip that has now been filed down just a little
Here you see the way the tip is filed down on both sides.
After filing, the now too sharp edge of the tip had been slightly blunted with a
water stone
