I'm all about being a good neighbor, but I might have to start being a jerk. Lending out tools to people who don't care about tools is a quick way to get my pressure up. I lent out some wire cutters. They weren't that expensive. However, when I don't get them back, that forces me to replace that tool when the neighbor should have been the one to buy the tool in the first place.

Anybody else not lend out their tools anymore?

I never lend out tools.

I rarely borrow thing to others, if I do I often come with it.

It's ridiculous how many people don't know which tool to use for a job. Even when the proper tool is in the toolbox, they grab the wrong one and try to (ab)use those.

People how do know tools, generally also have them.

Only to those I KNOW, who i know they KNOW what they are doing. These are the people who have shown they will return things in the same or better shape. If something didn't come back then they don't get a second chance (unless there is an exceptional reason).

I consider it part of being neighbourly to lend cheaper tools even if the odd item is misused or lost. Best to "play it safe" in case of ever needing a favour from them.
Many on these forums prepare in relatively elaborate and expensive ways for various sorts of doom, indeed discussion of such preps is arguably the main purpose of these forums.
IMHO, a vital and sometimes neglected part of such preps is to be on good terms with neighbours whose assistance you may need in an emergency.
In my view it is foolish to spend perhaps thousands of £/$ on supplies and equipment and yet to risk being on poor terms with a neighbour for want of lending them a £10 tool.

I am rather more reluctant to lend anything expensive or that requires special care in its use, or that is particularly dangerous if not used correctly.

Things to lend readily, screwdrivers, hammer, pliers, wire cutters, basic flashlight, mole grips, hex keys, spanners, cheap hacksaw or bow saw, extension cord, garden hose, and similar items that are cheap to replace and/or not easily broken.

Things not normally lent, power tools, axe, chainsaw, anything that needs special care in use, anything no longer manufactured and therefore not readily replaced, anything expensive.
I would also be very reluctant to lend anything specifically "doom prep related" since I believe in keeping such matters private.

Just curious, what kind of items are you talking about?

Geiger counters, gas mask, bulk chlorine tablets, Katadyn water filters, combat knife, crossbow, two way radios, lock picking equipment, breaking and entering equipment.

Being on good terms with your neighbors is always an excellent idea. However, I'm not sure a neighbor who borrows my tools and never returns them is a person I could rely on in any sort of emergency.

Agree entirely.
But firstly they might well turn out to a thoroughly reliable person who DOES return the items borrowed. You wont know until you try it, some posters suggested not lending things in case.
And secondly whilst someone who omits to return borrowed items is indeed not someone to rely on during an emergency, still better an unreliable friend than a potential enemy.

I see 'adam2' includes lockpicking gear in his survival kit. The Black Scout' survival site has lots of this for sale. But I've never understoodd why. What is the purpose of including it?
That is the crime of 'going equipped to steal' in Britain, so not an option. Is it recommended for US surival kits?

as regards lending there's the Old Irish Saying:

'It's better to give than to lend - and it costs the same' :-).
