Here's a design flaw, or at least a UX drawback, of the traditional surgical scalpel: Changing the blade requires using a separate tool, like a pair of forceps. Here's a medical professional's quick demonstration of how to change a scalpel blade:

However Bayha, a German company that's been making surgical tools since the early 1900s, has invented a tool-less scalpel changing system.
"Thanks to the locking system, the blade can be inserted and removed from the scalpel handle without touching the cutting edge. No blade remover is needed to remove the blade. The shape of the blade mount and the quick-release system of the scalpel with a bolt ensure that the blade sits firmly in the handle and guarantees a safe and precise cut."
Ejecting the blade is similarly easy:
The company offers a variety of blade styles.
These were designed for surgeons and veterinarians, but over the years Bayha's high-quality scalpels have gained popularity with tradespeople and craftspeople as well; thus the company offers less expensive non-sterile versions of the blades, for those cutting into materials rather than people.
There are six different handle types available:
They also offer a safety cap that locks in place magnetically (a nice touch), for surgeons that like to use the same blades over and over again. Just kidding, the safety cap is of course for tradespeople.
Unlike surgeons, tradespeople occasionally have a need to work overhead. For handles No. 4 and No. 6, which tradespeople prefer, Bayha also offers wrist straps. Dropping the tool no longer requires climbing down from the scaffolding (or fetching the first aid kit for an unlucky assistant).
Sorry, fellow Yanks: Bayha does not appear to have U.S. distribution.

Function all the way, none of the fancy stuff. Yet still elegant, very cool!
