It's the teal color, so it's extra rare for collectors. Understood the "hoarding" or "collecting" of tools. But never as "works of art" or that the tools will "go up in value". They are tools to be used.
Kind of like Pokemon cards, you got to collect all the colors. But in other collecting hobbies like trading cards, coins, vide games, there are grading systems, and you can get the slabbed and encapsulated in plastic and assigned an overall numerical grade based on the wear of the item. But on tools... why spend 18k on them to collect them all and not use them, hold onto them and hope they go up in value? Maybe I should start a tool grading company lol.
