The AC Infinity Pruning Shear 8″ Bypass is a bypass hand shear for cleanly cutting thicker stems and branches. Drop-forged steel blades with a Teflon non-stick coating, spring-loaded handles with a soft rubber grip, a sliding safety lock and a side switch that opens the jaws wider for cuts up to 16 mm (5/8 in). Quick Bloom Lights is the official Australian importer for AC Infinity: stocked in Sydney, shipped domestically.
Drop-forged bypass blades
On a bypass shear the sharpened blade slides past the lower jaw like a pair of scissors, so it slices through a stem rather than crushing it. AC Infinity design it for exactly that: a clean cut on thicker stems for quicker recovery and regrowth. The blades are drop-forged steel with precision-ground edges, and a Teflon non-stick coating stops residue building up and jamming the action.
Adjustable opening for thicker cuts
A side switch sets how wide the blades open. The narrower setting keeps the grip span comfortable and the cut controlled for everyday work; switch to the full opening (up to 20°) when a stem needs it, and cut capacity rises to 16 mm (5/8 in).
Spring action and safety lock
Spring-loaded handles push the blades back open after every cut, and the ergonomic soft rubber grip spreads the load across your hand, so heavier cutting takes less effort over a long session. A sliding lock holds the shear closed when it is not in use, protecting the blade and your hands.
Pick the right shear
AC Infinity make four hand shears and Quick Bloom Lights stocks all of them. They share the same Teflon non-stick coating, spring-open handles and sliding safety lock; the difference is the blade and what it is built to cut.

FAQ
Bypass or micro-tip — which do I need?
Use the bypass for anything thicker or woody, up to 16 mm (5/8 in). For fine detail work, small snips and trimming close to other growth, the 6.6″ micro-tip shears are more precise — the straight for open cuts, the curved for reaching into dense growth. The bypass and one micro-tip together cover almost every cut.
How do I look after the blades?
The drop-forged blades are ground for the heavier cuts a bypass shear is used for, and the Teflon coating keeps residue from sticking. Like any quality cutting tool, it lasts longest if you wipe it clean and dry it after use rather than putting it away wet.
What does the side switch do?
It changes how far the blades open. Use the narrower setting for everyday cuts; switch to the full opening (up to 20°) when you need it for stems up to 16 mm (5/8 in).
How do I keep the blade clean?
The Teflon coating stops most residue sticking; wipe the blades after a session and keep the action free of build-up. The straight shear with cleaning kit includes a jar and slotted sponge if you want a dedicated cleaning setup on the bench.
