I used to be more of a collector than I am now, at one point I owned a dozen or more of William Henry T10 folders with various scales as well as a few T12's and T15's lovely knives all and I even get to visit one of the T15's when I am near Syracuse NY when I grab coffee with my friend
Peregrin
he also has a small collection of Gary Graley knives

But any more those William Henry knives are worth a small fortune...coulda...woulda...shoulda

I moved those when I needed to pay for something else, where a 'true' collector doesn't part with his collection.
Here's a snapshot from back in the day of some of my William Henry's

And Sebenza's at one point were piling up everywhere! But those too have moved on to folks with a need for some Sebenza in their life too

Do I miss them? you betcha, but I have always managed things so that I only buy what I can afford at the time, never used my day job paycheck as that was just for the family and household. Money for my 'toys' always came from what I could save up from my leather work, or from selling one knife to buy the next. That has kept the wife quite happy

so she never worries when packages arrive as she knows I have it covered elsewhere.
And now I am whittling down the few knives I have left to just a select set of knives, leaning more towards small fixed blades.
The Pena X series has a nice look to them and they always draw my attention, but for one reason or another I think I have kicked that particular habit...for now at least
