Henckels

Serrated steak knives can't be sharpened so if yours have dulled over the years, there's really only one option. For a nice, new sharp set at a nice low price, grab four Henckels steak knives in white, black or red for just $30 -- down from $50. 

Right now, many of AeroGarden's popular indoor smart gardens are as much as 50% off when you use code HOLIDAY20 at checkout. That includes the popular Harvest Elite down to $90, the sleek three-pod Sprout for $50 and a microgreens garden kit for just $32. 

While all of these are excellent deals, my pick goes to the hefty AeroGarden Bounty Basic, which has enough room to grow nine plants. It's down to just $140 right now (originally $300). See some top picks below and shop the full inventory of smart garden deals here.

Coravin

This is the one gadget wine drinkers gush over. The Coravin Timeless allows you to taste from as many bottles as you want without popping the cork. It extracts wine through a hollow needle and repressurizes the bottle with argon gas to prevent it from going bad.

NutriBullet

This machine has power in spades and looks nice atop your counter. You won't likely find a 12-watt blender for much cheaper than this.

SodaStream

Ready to kick the can and save loads on that monthly seltzer spend? Grab an easy SodaStream Terra while it's at an all-time low price. Plus, a whole slew of other SodaStream machines and bundles are as much as 36% off on Amazon right now.

Shun

A Japanese-style knife is great for precision cuts and this smaller 6-inch Shun is the perfect sidekick to your big Western-style blade, which is better for laborious chopping. Grab one of Japan's sharpest exports for 33% off at Williams Sonoma right now.

Nespresso

If you prefer a sleeker pod coffee maker, Nespresso has the look down. A slew of the brand's pod coffee makers are on sale at Amazon. The Vertuo Next by Breville is down to $127 and comes with a set of capsules to get started.

Instant Pot

This lid turns your 6-quart Instant Pot into a powerful air fryer. I've tested dozens of air fryers and this unit blasts food into crispy goodness as well as any of them. Plus, it's a big space saver if you already have an Instant Pot.

It's currently down to the lowest price we've ever seen it. 

Vitamix

There's a chance we'll see certain Vitamix blender models drop lower than 27% off, but nearly the entire line is on sale at Amazon, including the Explorian down to $290. It's available in red, slate grey or black at this reduced price.

Brewvana

Trying to find a great gift for a beer lover? Brewvana is an excellent beer subscription service, but you can order one-time boxes including the 12 Beers of Christmas Box. It's normally $95 for 12 handpicked brews from microbreweries around the US, but nab two or more and you'll get 10% off your order with code HOLIDAY10.

The Christmas beer box ships on or around Dec. 15 and will likely sell out.

Anova Culinary

Sous vide cooking is easy to do and should turn out perfectly tender steak and fish with very little effort. You'll need a precision cooker to get it done though, and Anova's smaller stick is down to $99 right now.

Instant Pot

This is the largest Instant Pot and has plenty of capacity to cook for large groups. Get it while it's down to an all-time low price.

Lodge

Lodge has been making quality cast-iron cookware for 125 years, so you can be sure it knows what it's doing. You can snag a 10.25-inch cast-iron skillet for under $20 right now.
