I recorded using a zoom h6 with an xy mic and foam screen and tripod. I sharpened a knife on a granite rock in front of the mic. I started sharpening the mic at a slow pace and then a fast pace. Recorded for a school project for a sfx library.
Bouncing two throwing knives off each other. It sounds kind of like those magnet toys that you throw up in the air and they make a warbling sound when they come together. Recorded with a tascam dr-40.
Rubbing my finger across a kitchen knife. The knife has a smooth part and a part with little indents, so there are sounds with each sample. Recorded with my lumix g7 camera with rode video micro attached to it.
