I am talking about idle time, not while in use. If you accidentally brush up against a really sharp edge it tends to catch on your skin and dig in.
Idle time for a knife , is the same as idle time for a firearm. It is the responsible of the owner , or person who used it last , to know where it is and if it poses a threat to others. If it poses a threat , you adjust it's storage or maintain possession until a safe storage can be had.
Regarding knife blocks verses drawers for knife storage, my wife and my son's fiancee keep taking knives out of my knife block and stuffing them in a drawer.
Sounds to me like you have some around you who fail to change their ways to be safer , then it is up to
you to find another way to instill safety, is it not ? Just like a firearm , would you accept if they borrowed it and just tossed it on the coffee table when done ? Or if they borrowed your car and returned it by parking it on the sidewalk ?
A knife is no different.
In our house , it is known , the knife is returned to the block ASAP when you are done , if you have to wash it first , so be it , but it does not get left laying on the counter. They all know , if they do , there will be hell to pay , and believe me they will get the lecture. I have a wife and 3 sons ( ages 6-16 ).
It is always up to the user to protect themselves and others from "accidentally bumping , bumping or snagging on it " , it is responsibility of use.
Adjust the software , not the hardware
It's an education issue , nothing less , the only thing that can change is to make the people safer. But as long as there are those who are unwilling to understand simple safety , the situtation will not change.
Look at it this way , you boil water , you go to pour it into a cup , would you leave your hand over the top of the cup ? NO ! Why ? Cause you realize that you will get burned so you move your hand.
In your case Jeff , all parties know there are sharp knives in the drawer , after 10 years if they can't remember that and be extremely careful when going in that drawer , nothing you can do short of key locking that drawer will make them safer from the contents.
