This is a high quality, durable and well-designed multi tool pocket knife from Victorinox. It has all the basic daily tools I need when I am travelling or camping. I fix some of the stools and lights with this tool when I could not find my screw drivers. The knife is really sharp. Since the spring system is pretty tight, I always make sure I handle it carefully to not cut myself when i open and close it. The cork screw driver is not that useful since it is small and I need to put in a lot of strength to get the cork out. The bottle opener is very handy especially when drinking on camp nite and house party. This tool is heavier than other ordinary multi tool set. If you forgot a pen and toothpick, there is a secret compartment which store this two tools. Awesome multi tool kit!!
