No Accurate Count
But, along the same vein as hso, I'll say more than ten.
Just for perspective, I don't have an accurate count of my Buck knives. Something happened a couple of years ago, and the count just took on a life of its own.
Spread across other brands, I have three tool boxes that are pretty well stuffed, and then three or four drawers, and then I have a desktop (table, actually) that's littered with them. And then a couple of banker's boxes.
One of these days when I have nothing else going on I might attempt an accurate census.
Trouble is, just like with a regular census, you start at one and, and by the time you get to the other end there's been breeding happening in there somewhere, and the tally is already wrong.
