Please skip this post. Just go buy an X-acto knife, a box cutter, or something with a handle. I’m not responsible for any digital dissections caused by my example.
Okay, so here’s the AWESOME way to cut plastic.
Get a pack of razorblades meant for a box cutter. Don’t bother buying the actual box cutter, as it usually just comes with one blade and it’s several times the price of just a pack of blades.
Hold the blade tightly between your middle finger and thumb while the bottom edge rests against your ring finger. The ring finger is mostly there to balance out the pressure you’ll be applying on the top of the blade with your index finger.
So that’s how to hold it, and you cut with pressure provided by the index finger.
“But Matt,” you might say, “that seems like you’re just being cheap. And isn’t that dangerous?”
Five blades for under a dollar is so worth a severed finger While five blades for under a dollar is a much better deal than close to $7 for a box cutter and blade, it’s not just an economical choice. Observe the positions carefully and you’ll find I have much greater maneuverability than just a blade with a bulky box cutter attached. Even the often lauded X-acto knife is just another awkward stick when compared to the small size of the blade itself. And while I wouldn’t recommend using just the blade on one of those, a boxcutter’s razorblade hefty enough to handle and thick enough to resist breakage.
Sometimes it’s not the most comfortable, but it’s definitely the most agile.
Using a razorblade also leads to careful cutting. Single action revolvers are often cited as more accurate for gunslingers, because (unlike dual action) the trigger just releases the hammer. If you have to cock before you shoot, you’re more likely to be mindful of your aim. If something is quicker and easier, there’s more chance a person fires away all willy nilly.
With say, a dremel, plastic obliterates before the easy press of the spinning bit… So easy that you must be extra vigilant in how much of that material is ate away. One quick twitch and there goes a vital part.
A razorblade has a similar set of circumstances, in that ‘one quick twitch and there goes a vital part’ applies less to the plastic and more to you!
So be careful and keep all fleshy bits away from the business end of the blade.
See you all tomorrow for the start of Ironhide week. :)
