Kosher razors?

I’ve had a pretty large beard for the past 15 years, but got bored the other day and used clippers to cut it down to just a mustache. It started as a quarantine joke, but I actually like it a lot.

I still want to stay “kosher” by not shaving with a razor, but am wondering about these. They’re designed for black guys because many of them tend to get bad razor bumps from traditional razors. It seems like they don’t “lift and cut” and claim to “minimize” contact with your skin.

Are these kosher or should I invest in an electric shaver?
