Victorinox Compact is one of the best knifes to carry every day.
Being in a city I do not need all the tools swiss army knife has to offer and choose wisely ones that I might need. Having a victorinox climber plus that has three layers of blades I take the climber out of my pocket because it is a bit bulky. Victorinox Compact is a two layer 91mm knife with excellent scissors similar in size and function to Climber plus ("plus" means it has a pen, pin and tiny screwdriver in scales/corkscrew same as compact).
In a pocket carry two layer Swiss army knife is much better then slightly larger three layer knife. While some people chase a knife with as many features as possible it seems like they miss on what a good tool has to offer.
Adding more tools sacrifices the usability of existing tools. For example using the main blade on a 3.5 inch wide SwissChamp is not anywhere as convenient as on Compact. But SwissChamp compensates that by being a better paper weight and excellent bragging subject.
The main blade is not locking and tiny bit shorter then 2.5 inches which is great areas where there is a 2.5 inch blade legal restrictions. Also well recognized shield and cross logo may play an important role for social acceptance a factor that many people seem to skip when choosing a knife.
To squeeze all the tools into a two layer knife victorinox combined the bottle opener with a can opener which works just as well for cap lifter and as a can opener it kinda punches through the can instead of cutting. I've noticed that some people go counter clockwise direction (right-handed people) when opening a can while clockwise works best for me as you continue cutting the can instead of starting a new hole- it's more efficient and makes smoother edge. (however the non-combo victorinox can opener is different and counterclockwise is the way to go)
One thing to do when opening a can is please make sure you cut the lid completely before throwing a can away - what may happen is in a trash an animal may find that can, smell the leftover of food and stick a paw or a nose into the can and if the lid is not cut all the way and pushed inside it will let into the can but may work as a trap on the way out!
In some of my victorinox knifes I did sharpen combination opener blade a bit at a "dull angle" of about 45 or duller on one (right) side only in favor of can opener cutting abilities and I also use that blade for opening boxes - you don't need a very sharp blade to cut the tape along the box folding edges and a sharp blade may cut through the box and damage the content of the box. And also having somewhat sharp edge helps for initializing some light duty prying. And using the combo-opener more saves the main blade. Making the bottle opener sharper may however cut through the top instead of lifting the cap. The screwdriver is about 6mm wide and most of the screws i'm dealing with are ether wider or narrower and unlike some other knifes does not doubles as "X"-phillips screwdriver - I do not however discourage people from trying.
I wish the knife had an awl or a "phillips" ...but it has the "parcel hook" with a nail file which is a good waterproof surface for strike anywhere matches. To use a pen you can open a hook and put a pen into the slot and close the hook over the pen to keep it in place. If you find it is easier for you to use a pen that way it justifies parcel hook presence on the knife :)
The key to the truth on the knife is a good tool not only to open wine but to untie shoelaces or other knots. It is the tiny screwdriver that holds the pin in scales not the corkscrew as some people think. If not the friction in scales the pin may fall right through the middle of corkscrew spiral unless there is a screwdriver.
Also if you think you will be opening more then one bottle of wine you might want to protect the eyeglass screw driver from disappearing. Consecutive opening bottles of wine may seem to make it harder and harder to keep track of that little screwdriver to extend that the whole knife can disappear.
Compact is a great lightweight (64 grams) compromise of the tools to have on you all the time. If you need something smaller perhaps key chain size - take a look at it's smaller 58mm brother the "Manager". And if you carry knife in your bag - you might want to consider more tools (climber-huntsman plus)and perhaps for less money.
I hope this is helpful, feel free to comment and enjoy!
