I'll put on my nerd glasses:
Spiders tend to be unsettling because they use hydraulic systems to move their limbs. They have some muscles for curling them back, but it's a series of blood-filled pumps that give them that unique creeping locomotion. Insects tend to use muscles for extending and moving their limbs. It's this hydraulic system failing when spiders die that cause them to curl up.
Fascinating creatures. Fun fact, they are not related to insects in the slightest. They diverged from that line of arthropoda some 500 million years ago making bugs and insects more closely related to us than to spiders and scorpions. Also, there have been cognitive tests done on specific species of jumping spiders that demonstrate forward thinking and planning strategies where they have a concept of location and future orientation by observing them zeroing in on a larger but more dangerous prey, then crawling out of the line of sight of said prey and climbing to a higher attack point from above. It was long thought that only larger more complex brains were capable of such things and that spiders were only reactive to stimuli.
Anyway....cool knife, but it looks like if someone typed "Spyderco Knife" in an AI image generator.
