Flymo 18V SimpliCut 450 Hedge Trimmer (with battery and charger) — 45cm dual action blades

Key takeaways

If you’re trimming hedges regularly, the Flymo 18V SimpliCut 450 is one of those tools that aims to make the job feel less fiddly. It’s cordless (so you’re not managing a lead), and it’s built around 45cm dual action blades designed for an even cut without needing repeated passes.

Where it really fits is straight-edge trimming and shaping curves, thanks to the loop handle that lets you adjust your grip. It also comes with a battery and charger, so you can get going straight away rather than waiting on separate parts.

That said, there’s a practical limit: it’s positioned as a garden hedge trimmer for everyday pruning, and it may not be the right answer if you regularly tackle very thick growth or want something heavy-duty for long, demanding sessions.

At a glance: what you’ll use it for

This is a hedge trimmer with 45cm dual action blades and a stated branch-cutting capacity of up to 15mm. The pitch here is simple: more consistent cutting should mean fewer repeat strokes, which can be a real time-saver when you’re doing a tidy-up around boundaries.

Because it’s cordless, it suits gardens where hedges are close to paths, where extension leads are awkward, or where you just don’t want cable management. Over an afternoon, the difference between “working around a wire” and “moving freely” becomes obvious, especially when you’re stepping along the hedge line.

What matters most in use

Two details stand out on paper.

First, the dual action, laser-cut diamond-ground blades are intended to produce a smooth finish and an even cut of branches up to 15mm. The “no need for multiple passes” idea matters if you’ve ever had to go back over the same section to tidy stray bits.

Second, the loop handle is designed to reduce strain and improve control. In real terms, that’s the kind of design that can help when you’re alternating between trimming straight edges and shaping a more rounded profile.

Worth noting (a limitation to consider)

If your hedges regularly include thicker, tougher branches than the stated 15mm, you may find the results are less consistent and you’ll have to slow down or reassess whether a more heavy-duty approach is better.

Easy storage and day-to-day practicality

Small things can make ownership nicer, and this one includes a built-in storage hook. That’s handy if you’re tight on space in a shed or garage, because it gives you a straightforward way to hang the trimmer securely rather than leaving it to take up bench space.

Who it suits (and who should skip it)

It makes sense if you want a cordless hedge trimmer that’s geared towards routine hedge maintenance—keeping growth under control, tidying edges, and shaping curves—without cables getting in the way.

It might not suit you if you’re after maximum power for heavy-duty pruning, or if you frequently need to cut branches thicker than the stated capacity. In those cases, a more demanding tool category is usually the safer bet.

Mini FAQ

Is it really cordless for trimming around the garden?

Yes. The description specifically frames it as “forget about power cords”, so you can trim freely without an extension lead.

Will it handle thicker hedges?

It’s stated to cut branches up to 15mm. If your hedges often exceed that, you may need to consider a different approach.

Does it come ready to use?

It’s listed as including a battery and charger, so you shouldn’t need to source those separately to start.

Can I store it neatly?

A built-in storage hook is included to help hang it securely in your shed or garage.

Should you buy it?

It’s a solid pick if you’re looking for a cordless, control-focused hedge trimmer with dual action blades designed for smooth, even cuts up to 15mm—particularly for tidy-up sessions and shaping hedges around the garden without managing a cable.

Better avoided if your main job involves thick, tough growth beyond the stated capacity, or if you want a tool that’s clearly aimed at the most demanding, long-duration pruning. As always, it’s worth checking your hedge type and branch thickness before committing—on this one, capacity is the main deciding factor.
