What tool(s) have gone missing?

I've misplaced too many things lol. Most recent was my Snap-On 30 led cordless rechargeable flashlight ($160). Well, actually I've lost it twice.... The first time I left it on top of a transmission and my S0 guy sold me just the light for $70. Not even a month after I did it again Now I am on my 3rd light and this thing never leaves my sight...

I've lost a ton of stuff, mostly channellocks and cans of pipe dope. Working out of service truck its easy to set stuff down and get distracted. Sometimes when its snowing stuff gets buried.
