Tefal 3in1 Optichef Hand Stick Blender HB643842 (1000W) with 20 speeds, chopper & 800ml beaker
Product description
What you get and why it matters
If you’re looking for a single hand blender that can do more than just blend soups, the Tefal 3in1 Optichef HB643842 is built around that idea. It combines a stick blender with a 500 ml chopper and includes an 800 ml beaker, so you’re not limited to one “type” of prep. On paper, the mix is aimed at everyday cooking: blitzing sauces until smooth, breaking down vegetables for batch cooking, and chopping ingredients without having to drag out extra gadgets.
The standout theme here is speed control and blades. You get 20 variable speeds plus a turbo function, so you can dial in gentler blending for things like creamy bases and go more aggressive when you’re dealing with tougher ingredients. There’s also “Powelix Blades Technology”, which Tefal positions as smoother, more creamy results and up to 30% faster performance compared with its own classic 2-blade approach. It’s a marketing comparison, sure, but it still tells you what the manufacturer is optimising for: texture.
The essentials: speeds, turbo and smooth results
The 20 speeds and turbo button are the kind of controls that make a difference in actual use. Blenders can be frustrating when they only have a couple of steps, with more granularity, you’re more likely to match the speed to what you’re processing. For example, you might start at a mid speed to break down cooked veg, then nudge up to finish into a consistent purée. When you switch between tasks (blending vs chopping), that dial-based control tends to feel more intuitive than repeatedly swapping settings.
Worth noting that “turbo” isn’t the same thing as steady blending. It’s best treated as a momentary boost for quick work, not the way you’d want to run everything continuously. If you prefer a more hands-off approach where you can press once and forget it, you may find yourself using the dial more than expected.
Where it stands out: the chopper and anti-splash guard
The convenience part is the 500 ml chopper. With a dedicated attachment you can chop, dice and purée a range of ingredients. That helps if your routine includes things like prepping onion/garlic for cooking, turning cooked vegetables into a smoother mash, or quick ingredient prep for meals later in the week.
There’s also an anti-splash guard. No gadget eliminates mess completely, but reducing splatter is genuinely helpful when blending sauces, soups, or thicker mixes—especially if you’re working over a saucepan and don’t want to clean the surrounding area afterwards.
Finally, the unit is described as having a non-slip soft grip for better control even when hands are wet. That sounds like a small comfort feature, but it’s the sort of thing that matters when you’re blending hot ingredients and you’re moving the blender around.

Practical buying check: what to watch before you commit
This blender is clearly positioned as a mid-to-strong “do more with less kit” option, rather than a purely basic hand blender. The question is whether you’ll actually use the included chopper and the extra attachment time. If your household only ever blends smooth soups and never chops or dices, you might not need the full 3in1-style setup. On the flip side, if you regularly do batch cooking or small prep jobs, the additional functionality is where the value tends to show.
Also consider how you prefer to work. With 20 speeds, you’ll get better control, but it’s still a manual process—you’ll be steering the blending, especially at higher speeds. And while the anti-splash guard helps, thicker mixtures can still be messy if you rush the blending or move too quickly.
Who it’s for (and who should skip it)
It makes sense if you want one appliance for blending plus a dedicated way to chop and purée, with plenty of speed control. You’ll like it if you care about getting smoother textures without constantly stopping, and if you value the ability to adjust speed on the fly.
It might not be a great match if you prefer very simple controls, or if you only blend light liquids occasionally and don’t want the extra chopper parts in your storage routine. And if you’re the kind of buyer who expects “set-and-forget” automation rather than steering with the dial and turbo, you may find the experience more hands-on than you hoped.
Care & maintenance notes
Dishwasher safe parts are mentioned, which is convenient for keeping up with day-to-day use. As with most stick blenders, you’ll still want to rinse or clean promptly after thicker ingredients—especially anything sticky—so the parts don’t dry with residue.
Mini FAQ
Frequently asked questions
Is this hand blender good for thick blends? It’s designed for smooth, creamy results and includes an anti-splash guard. That said, the thickness of what you blend and how carefully you move the blender still matters.
What does the chopper attachment add? It’s a 500 ml chopper designed to chop, dice and purée ingredients, so you can do prep tasks without switching to a separate appliance.
How many speed settings are there? You get 20 variable speeds plus a turbo function.
Are parts dishwasher safe? The description states that dishwasher safe parts are included.
Final verdict
When it makes sense, The Tefal 3in1 Optichef HB643842 is a sensible pick if you want strong everyday blending with finer speed control, plus the extra help of a 500 ml chopper for chopping and puréeing. It’s especially appealing if you care about texture (Powelix blades) and like the idea of reduced splatter (anti-splash guard).
When to skip, You may want to look elsewhere if you’re after a very basic blender and won’t use the chopper, or if you prefer minimal manual control. It’s not perfect for everyone—more controls means more steering—but for most people cooking regularly, that extra control and 3in1 setup is exactly the kind of convenience that gets used.
