When I saw this clip, my stomach sank.

I had this feeling watching Jackson excitedly slice a cucumber…until he sliced his fingertip off instead.

I have knicked myself on mandoline blades countless times in professional kitchens.

6.And, ALWAYS look where you’re slicing.

It’s not like typing, it’s possible for you to’t look away and keep your fingers moving.

So, if you’re feeling extra cautious, get your hands on one of these nifty mandoline guards!

I hope these tips help you feel confident wielding this infamous kitchen gadget.

And remember, watch your phalanges!
