Kynup Garden Secateurs: Love the Blade, Watch the Lock
One buyer keeps theirs shut with an elastic band. Another calls the catch better behaved than any pair they've owned. Kynup's SK-5 secateurs cut brilliantly - the row in the reviews is about everything wrapped around the blade.
“These secateurs cut through branches like they’re personally offended they grew there.” That's Mick, one of the five-star reviewers, and on the subject of the blade he speaks for nearly everyone. Whatever else buyers disagree about, and they disagree plenty, almost nobody claims the Kynup Garden Secateurs don't cut.
The real argument is over everything wrapped around that blade: a slide lock that some buyers rate and others have replaced with an elastic band, a spring that lives loose between the handles, and a 25mm cutting claim that one very thorough reviewer put to the test on a rhododendron. The hundred most recent UK reviews sort it all out fairly cleanly, and the pattern is worth seeing before you add a pair to your basket.
First, the Part Nobody Argues About: The Cut
The blades are SK-5 high-carbon steel in a bypass arrangement, meaning the sharpened upper blade slices past a curved lower jaw rather than crushing down onto a flat anvil. On live wood that's exactly what you want: a clean cut that heals over quickly instead of a bruised stem that lets rot in. Kynup grinds these properly at the factory, and sharpness is comfortably the most repeated word across the reviews.
Les Lithgo, five stars, calls them “super sharp and tackled much larger branches with very little effort”. Marilyn, also five stars, says they cut “through thick rose bushes etc quite easily” and are “not at all flimsy”. Seventy-six of the hundred most recent reviews award full marks, and most of them read along those lines.
One warning arrives with unusual credibility. A five-star buyer wrote: “Excellent quality and that sharp I took the top of my finger clean off with medical precision. Take care!” They still gave the tool full marks, which tells you something about the blade and something about the British gift for understatement. Treat a new pair the way you'd treat a new kitchen knife for the first week.
The Slide Lock Divides the Room
Now the controversy. Kynup's own listing promises a “Reliable Safety Lock”, yet eight of the hundred most recent reviews complain about the slide catch that holds the handles shut, and they don't complain gently. John H gave two stars: “the locking mechanism is as sharp as the blade. Cut myself trying to lock it closed.” Karter 1 went one star: “secateurs pop open easily which can be quite dangerous. I have resorted to putting elastic band round handles. Shame because the cutting is good.” A three-star reviewer found the clip “fairly poor and doesnt engage most of the time” (sic), and three of the sample's eight one-star reviews describe a lock that broke early or never worked at all.
The twist is that five other reviewers single the same catch out for praise. Jonah73 reports “the locking button works well”, and W A G likes that “the lock button is not in the way like some secateurs”. A split that stark usually means manufacturing variation rather than a design everyone hates: some catches leave the factory crisp, others sloppy. So test yours the day it arrives, lock and unlock it twenty times, and send it back if it pops open. Amazon's return window beats an elastic band.
One more caveat. Benjamin Bruce, a left-handed four-star reviewer, notes that the lock “requires you to hold them in your right hand to use the locking mechanism”. The listing calls the tool balanced for both hands, and for cutting that holds up, but lefties will be flicking the catch with their off hand.
The 25mm Claim Meets a Rhododendron
Kynup advertises clean cuts through fresh branches up to 25mm, a full inch. B Healy, whose three-star review is the most thorough test in the sample, wasn't convinced: “Realistically 15 to 20mm max is possible.” At the full 25mm the curved lower jaw couldn't keep the branch seated, a 20mm rhododendron stem “was a mission”, and on dry, hard wood over 10mm the verdict was blunt: “forget it they are too hard for these”. A fat green rose stem, on the other hand, cut fine.
That squares neatly with the happier reviews once you read the sizes. bullybeef, five stars: “used them on branches up to half an inch, cut loads and still going strong.” Half an inch is roughly 12mm, and inside that range there isn't a single capacity complaint anywhere in the sample.
So set your expectations accordingly. Deadheading, rose pruning, cutting back perennials, soft fruit, green shrub growth up to finger thickness: all comfortably within reach. Woody buddleia stumps, dried-out apple prunings and anything thumb-thick belong to loppers or a pruning saw. To be fair, that's the advice we'd give with most bypass secateurs at any price. The 25mm on the box is simply optimistic.
Light in the Hand, Kind to Sore Ones
The handles are aluminium alloy under soft non-slip grips, and the whole tool is light enough that reviewers keep mentioning it unprompted. Antonia235 sums the pattern up in seven words: “Excellent sharp easy to use and light weight”. Another five-star buyer describes them as “Light, sharp secateurs with a nice grip. Just what I needed & at a reasonable price.”
For anyone whose hands are the limiting factor, Rober's five-star review is the one to note: “Great product easy to use with arthritic hands”. That fits how the tool is built. The spring does the opening work for you, the grips are chunky enough to spread pressure across the palm, and there's very little weight to lug around a border all afternoon. B Healy's rhododendron test did flag the flip side: smaller hands can run short of leverage at full stretch on the very thickest cuts. Stay under that 15mm mark and it isn't an issue.
One five-star buyer even rates the colour scheme as a safety feature: “being red they are easy to see if lost in garden”. Anyone who has laid a pair of green-handled secateurs down in a flower bed at dusk will understand completely.
How Long They Last Depends Who You Ask
Durability is where the reviews go both ways. Shelly K bought a pair in 2024 and reports: “They are still going strong and working effectively after more than 12 months.” The lock still locks, the spring is still fine, and they liked the tool enough to order a second set for tougher hedge work. Christopher Danks found his “still working well after 3 weeks of constant use”, and Raz, four stars: “Had these a few months now and still sharp. I used them daily before winter.”
Then the other side. Sims, two stars: “Lasted less than two months before breaking”. A one-star buyer says theirs “Stopped working within 6 months”. One three-star reviewer is on their second pair and reports both broke at the same spot, “weak on the blade tip which is prone to breaking”, and another three-star buyer found the edge dulled quickly. The box includes a spare spring, which is both a thoughtful touch and a quiet admission of the likeliest failure point. B Healy's marathon review explains why it matters: the spring isn't fixed in place, it just sits over two protrusions on the handles, and theirs fell out when the secateurs were dropped.
Two habits will stack the odds in your favour. SK-5 carbon steel holds an edge well but dislikes damp UK sheds, so wipe the blades dry after use and give them the occasional drop of oil. And a few passes with a cheap sharpening stone each spring keeps that factory edge alive. Cared for like that, plenty of owners are getting multiple seasons from a tool that costs less than a bag of decent compost.
The Verdict: A Strong First Pair, Bought With Eyes Open
The listing's lifetime average stands at 4.6 stars across 9,566 ratings. The hundred most recent reviews land a shade lower at 4.41, with the slide lock doing most of the damage. Our own take sits between the two: as a cutting tool this is a four-and-a-half-star performer for light and medium pruning, docked for a catch that isn't consistent from unit to unit.
Buy a pair if you're after a first set of secateurs, a spare for the allotment or greenhouse, a light tool for sore or arthritic hands, or a low-risk gift for someone starting out. Look elsewhere if you're left-handed and particular about locks, if you regularly cut thick or dry wood (ratchet loppers will serve you better), or if you want a buy-once tool with replaceable parts, which means spending several times the outlay on a premium pair.
For everyone else, the maths is simple: a properly sharp bypass blade, comfortable grips, a spare spring in the box, and one component to check the day it arrives. Test the lock, keep the cuts under 20mm, and you'll see why three quarters of recent buyers hand these full marks. You can check today's price on Amazon here.
