Since my childhood I love to collect different types of knifes. If including normal things like kitchen knives my collection is well over 100.
If I just count hunting, swords, folding, pocket, etc. knives it's gotta be around 50ish. I never counted.
Here's a stack of some things I Just pulled out.
18" machete (just under 46 cm)
Two bayonets' from WWII
A fixed blade knife I made when I was about 8 or 9.
Here's big and little brother for comparison

I can't even express how many box cutters I have lying around. They're super useful and the blades are great for tossing out and replacing if you're doing hard work with it.
And you can change out the blades for different applications.
Straight cut for opening things or breaking down cardboard, curved for roofing or carpets, recurved for modeling.
These Swiss Army knives were on sale some years ago at an outlet store that was going out of business.
I picked up a box of about 50 of them for about $2/knife. I still have maybe five myself. I've given the rest out to my friends, relatives etc.
These come in contractor packs of 5+. I've seen contractor packs with as many as 50.
I've got probably 20 of these spread out around the house, garage, and garden shed.
Katanas I take backpacking
City stick with the skull head, and sword cane with the rounded head.
The heads are interchangeable on them.
