I've not had to do it since I moved to Australia but the need came up recently. So I went through the drawers and such tallying up what I've found… The estimate came to just under $50,000. It was an eye opener that's for sure, considering the overall tally for the entire contents of the house was $110,000. I have two stationary tools, a lathe and bandsaw, that are collectively valued at $11,000. Other than that everything else is hand tools with a value of about $39,000. That's a lot o crap! What's more, I'm not a collector so I don't have 5 #3 planes, 22 saws, or anything like that they're, for the most part, one offs.
I'm not bragging but that's a lot of money spend on tools. And when you consider the average cost for an individual tool is about $200, that's a lot of tools. Half the houses insurance is in the garage. Don't think I'll share this info with the wife.
