I use these mainly for data center work and this is by far the staff's favorite tool. If you're pulling back a lot of cable, you'll often have to cut it. The knife we have has been used by many people in a 24/7 data center for over 5 years and is still very sharp. The only signs of wear are small scratches on the scissors from falling and the like. This is a very high quality product. I bought it for my home because I really like this set. Be careful of the oil on the blade so it doesn't rust or anything like that.
