This is going to get interesting ... Some say you can, some say you can't, some say they did, some say they didn't. However, with Ryanair it is actually quite clear. This is what Ryanair’s website classes as Prohibited articles for cabin bags:
8.10.1.2 Pointed/edged Weapons & Sharp Objects; pointed or bladed articles capable of causing injury, including axes & hatchets, cleavers, arrows and darts, crampons (grappling iron, hooked bar of iron, or plate with iron spikes used in mountaineering), harpoons & spears, ice axes & ice picks, ice skates, knives with blades of more than 6 cms including lockable or flick knives, ceremonial, religious and hunting knives, made of metal or any other material strong enough to be used as a potential weapon, meat cleavers, machetes, open razors and blades (excluding safety or disposable razors with blades enclosed in cartridge), sabres, swords and swordsticks, scalpels, scissors with blades more than 6 cms as measured from the fulcrum, ski and walking/hiking poles, throwing stars, tradesman’s tools with a blade or a shaft of more than 6 cms that have the potential to be used as a pointed or edged weapon, e.g.drills and drill bits, box cutters, utility knives, all saws, screwdrivers, chisels, crowbars, hammers, pliers, wrenches/spanners, blow torches.
In short: No, you can't. And if you fly out of Santiago airport, chances are they will be taken or you have to check them in.
