The honest split nobody puts in a listicle: a cheap pair of straight-blade shears is what actually cuts tape, packaging, dressings and the occasional pair of jeans a dozen times a shift. It is also the pair you will hand to a paramedic and never see again. Buy that pair in a two-pack and stop caring about it.
A rescue tool — strap cutter, ring cutter, carbide glass point, folding body — is a different object doing a different job. It is worth carrying in trauma and anything prehospital-adjacent, and it is dead weight in a unit where you spend the shift titrating drips. The mistake is letting the expensive one replace the cheap one; it should sit alongside it, in a different pocket, used a fraction as often.
