Use this sharpener: (or one like it) Drawing Pencil Sharpener for... https://www.amazon.com/dp/B0DTGQ9JG2?ref=ppx_pop_mob_ap_share Also - similar sharpeners available on Temu, pay attention to point length in sharpener descrption. You DO NOT want the ones that sharpen super long. Normal/Medium length to medium/long is good enough unless you do specialty effects. Since I used this, minimal problems with new prismacolors from Mexico (150 set) where they split with regular blade sharpeners and electric sharpeners. That being said, I still like the vintage 1986 and before prismacolor pencils (72 set). It's expensive but worth it if you get easily upset with crappy pencils. I have the Kalour brand and they upset me. I have many 1995 and after prismacolor pencils that upset me. Polychromos and Caran D'ache Luminance make me happy.
