i thought to cut radial arteries on my wrists as it's hilariously simple to locate em they're literally pulsating on the surface, used to roughly measure heartbeat etc. couldn't force myself for they border to locomotor nerves and in the case of fail id left with crippled hands. it's up to you anyway i've seen photos of people who successfully died slashing their wrists horizontally, possibly they had damaged radials AFAIK the scenes always had some type of anticoagulant to prevent blood clotting like alcohol, bath tub etc speaking of a cutting instrument. the one image showed a plain paper-cutter near the cadaver, the wound looked very messy like the person sliced the wrist over and over with full force to such extent it looked like halfway to amputation. i think it wouldn't work at all without precautions taken to prevent blood clotting and the forum can provide a ton of examples and cases to prove the method's unreliability. for example lostallhope.com rates cutting in terms of reliability like 1.6%. 2 out of 80
