I use the case with a 12.5cm Herbertzklappmesser handle length, weight 178 grams. The blade fits into it very well. The flap can be opened and closed easily. It is very convenient and also while sitting not noticeable. Unfortunately, after 6 months of use was frayed at the bottom of the case and my 75 expensive knife would have been almost lost. It would be better to put the price slightly higher, but offer a more durable finish. Probably suitable for smaller and lightweight knife. Not suitable for knives with a handle length about 12cm and a weight of 180 grams.
