I don't let _anyone_ handle one of my knives, let alone lend it to them!
It may seem harsh and not very friendly, but indeed is just being reasonable and knowing what you are going into.
SCENE 1
- Scuse me, can I borrow your knife a moment?
- Sure! Here it is.
The knife was returned more than 3 hours later
SCENE 2
- 'Scuse me, can I borow your knife a couple of minutes?
- Sure, here it is.
The knife was returned a couple of minutes later.
With three dents caused by trying to cut heavy gauge steel wire with it.
SCENE 3
- Hey! Cool, may I have a look at it?
- Sure. Be careful, it's so sharp you can cut without even knowing it!
- ok, I know what I'm doing... Hell! This is blood!!!!
SCENE 4
- Can I borrow your knife?
- Here. Take it (i open the knife)
The guy does what he needs to do, then tries to close the knife, without realizing it has a liner lock.
- Leave it to me, I'll close it.
- No no. I can close it, no problem.
The guy fumbles some more with the knife, pushing hard as he can on the blade with his fingers on the blade's closing path.
- GIVE IT TO ME, NOW! You ar going to chop your fingers off, you idiot!
- Oh... sorry...
SCENE 5
- May I look at your knife?
- Sure, here it is.
Before I can say anything the moron pulls his thumb on the razor sharp edge
- OUCH! What the hell! Why you keep it so sharp??? It's dangerous!
I take the knife back with some comment on the line of "It's a knife, its job is to CUT things, you idiot."
SCENE 6
- Can you lend me your swiss knife? We have to open a wine bottle.
- take it.
Five minutes later the knife returns with a badly bent corckscrew...
These all happened to me over several years. Reading all of them one after the other in a few lines, by SCENE 3 you were probably wondering why I was so stupid to go on and let scenes 4,5 and 6 happen.
Just because I thought that A or B were more "polite" options than C.
Now I think that is very impolite to have my knife damaged, and is as impolite letting somebody cut away pieces of his anathomy.
So, I don't want to have to look over every idiot borrows a knife to avoid they lose, mishandle, damage it or themselves.
If they damage the knife I get angry, if they damage themselves I feel guilty.
If somebody needs a knife he may very well buy his own and learn to use it.
I don't want to stay all the time eyes fixed on him, ready to jump if he does something stupid to avoid he injuries himself or damages the knife thru idiotic practices.
So, now I just say: No. It's a very expensive model and it's razor sharp, and a guy already cut himself badly with it so I don't lend it anymore. End of the story
If somebody is interested in knifes I explain him all that he wants to listen to, show him how to safely operate the various locking mechanisms and so on and are more than gladly ready to supervise him when he tries to learn to use a good knife. But I won't lend a knife to anybody for general use.
