Have the knife daily work reasons on a belt. The bag is equipped with push-button, which I think is much better than Velcro, because so does not open so easily provided from the sheath.
The blade is very sharp, also has a module for smashing car windows, which can be very useful in an emergency, because car windows are hard to break even with a hammer in an emergency.
The knife is easy to operate with one hand. The opening and closing functions with just the right voltage. This can still be traced via a screw if necessary.
Walther just stands for quality and you will surely last a lifetime with this product!
