What it is
A 2017 video from Shadiversity, a fantasy and medieval weapons channel, that asks which real medieval weapons and fighting styles would work for a tiny fairy-sized fighter. It applies ideas like the square-cube law and biomechanics to weapon choice for very small creatures.

For starters, you might want to take a look at what Shadiversity posted on YouTube regarding which kinds of weapons were most suitable for fairies: [this video] Basically, when thinking about what kinds of weapons a tiny sapient squirrel-like creature might want to employ in combat, you'll need to think about how the square-cube law (where every time you double a creature's size, you quadruple its surface area, and multiply its volume, and possibly mass, by 8x) would come into effect. Given how much stronger squirrels are for their size compared to humans, given how much higher they can jump, given how fast they can run, and given how real-life squirrels jumping onto you might make you jump (like

I think some people aren't thinking about how muscles and biomechanics work. If your pixes have a musculature anything similar to a human just smaller they will be proportionally much stronger per unit of body mass than a human. If a human were to try and wield a sword with a blade that was 3 meters long and half a meter wide, they wouldn't be able to lift it much less use it in combat. But a 15cm tall pixie would have no trouble wielding a weapon with a 30cm blade as long as its grip was designed for the pixie's smaller hands. Imagine an army of hundreds of pixies coming at you, each one wielding a large steak knife. Death from a thousand cuts, anyone? Here's a youtube video discussing the

I'm suggesting checking out Shadiversity and his "Weapons that a FAIRY could use", it should provide a relevant insight into the subject, since they're roughly the size of gmones or gremlins somewhat: [this video]
