Over the last year I've begun to keep my Swiss Army Knife with me more of the time. As it is obviously a pocket knife, non-locking and not that big it doesn't really pose any legal problems in most places.
It has amazed me the sheer number of tasks I have used it for. Rarely does a day go by in which it isn't useful at some point.
So far I've used it for:
- Speading jam on bread
- Taking the skins of sausages
- Cutting cheese
- Opening packets
- Sharpening Pencils
- Cutting the stems off flowers to put them in a vase
- Removing threads from clothing
- Removing plastic tags
- Trimming broken fingernails
Having two blades is also useful in general usage as well. The sheepsfoot blade, which I have convexed, is short and accurate enough for cutting away single threads and tags whilst the longer blade is good for the more kitchen based tasks.
The only problem is that when sitting in my pocket it does act as a fluff magnet. A quick clean with a cotton bud and squirt with WD40 usually keeps it in good condition though and to be fair I only use a whetstone or strop the blade most of the time as I rarely let it get dull.
