Gets to the bottom of the jar.

Keeps the PB off your hands. No waste tool for the kitchen. Great addition to my handy gadgets that sometimes gets a funny look by my wife.


We make good use of this knife.

We have an every 5 month delivery of Adams peanut butter from Laura Scudder’s. They are 6 large jars, 36 oz. each. This knife is great to use for smearing the peanut butter and also for cleaning out the last bit!
Love it. And we’ve given several as gifts too.

Perfect P.B Tool

Easy to use and to clean! Long blade is great for large peanut butter and mayo jars. With it I can give my Jack Russell the last bit of P.B. that he loves. Glad I ordered it.More > < Less


Deluxe! But one little suggestion.

7/11/2019 by Julia

I actually love this! Especially that it's long, so I don't get peanut butter on my knuckles. And I'm using the little tab at the end to get to the bottom of my jams and mayonnaise too. The red handle makes it super easy to find in a drawer. The one little improvement I'd suggest is a serrated edge somewhere, so I can use the knife to cut my sandwich after I've made it.More > < Less

Every Last Bite

Fed up with sticky knuckles and wasted food, Maker Landon Christensen created this peanut butter knife to help solve a common kitchen problem: getting every last bit of deliciousness out of peanut butter jars. Yes, even the big ones.

Landon pulled from his art background along with his PB&J-making prowess as a dad to create the PB-JIFE. The long, stainless steel blade has a curved tip specially designed to reach into all the contours of a jar and scrape the bottom, sides, and rim. But PB-JIFE is not just for when the jar is almost done. The strong, extra-broad blade is sturdy enough to stir peanut butter, natural nut butters, jams, thick oils, and other spreads, too. And it can deliver an ample portion to an eagerly awaiting sandwich with just one swipe. It’s one of the most helpful knives around—jar none.
