- The chance to fire a razor blade depends on the luck stat. The activation rate is equal to 1/(15 - Luck). At base luck (0), the chance is 6.66%, maxing out at 100% at 14 luck.
- Cricket's Body/ Compound Fracture/ The Parasite: When razors are fired, the split tears will also be razors and do quadruple damage. The Parasite's split tears look like normal tears.
- Dr. Fetus: Adds a chance for the bombs to deal increased damage. See the page for the specific damage formula.
- Glass Cannon: Adds a chance to fire a giant razor that does roughly triple damage.
- Haemolacria: Adds a chance for tears to do quadruple damage. Burst tears will also do quadruple damage if the main tear does quadruple damage.
- Technology Zero: When razors are fired, they will connect to other tears via electricity. The electricity also does quadruple damage.
- Lachryphagy: Tears can be fed to razors, increasing damage and splitting into 8 razors after a little while. If razors are fed to the tears, the razor damage doesn't apply to the tear both before and after splitting.
- Tech X: Overrides Apple!.
- Tough Love: With 14 luck, overrides Tough Love, as the razor blades do more damage anyways. With 13 luck, Apple and Tough Love each have about an equal chance to trigger.
- Both the item itself and the description is a reflection of one of Isaac's nightmares between floors that involves him finding a razor blade inside a piece of candy.
- The item and pickup quote are a reference to the urban legend of giving away candies with razor blades hidden inside of them as a way of harming people.
