lend tools, any tools.... not a chance. Dont mind helping out and cutting for someone but lend them one of my saws, no way on this earth. You learn the hard way, I was reluctant to lend a sledge hammer years ago, they said "I wont break it and if I do I will buy a new one" so I gave in. First swing at a posted he missed and cracked the handle, I had a new handle off him but thats not the point. You have the work of fixing it, even if they said they would fix it could you trust it to be a good repair, I think not. So NO, if they need tools let them buy their own instead of save off someone else's back.
