Here's an interesting product design that addresses one of those minor UX hassles we all know, but rarely consider.

The knife is produced and sold by Bosign, a Swedish product company founded by Hynell. It comes in Olive wood, as well as stainless steel or brass, in small and large sizes. Prices run from €15 to €50 (USD $18 to $60).
