Garden Pruner Pro.
Garden Pruner Pro. shears that have titanium coating. have a high corrosion resistance, due to the protective chromium oxide layer that covers the steel surface after heat treatment.
Garden Pruner Pro.Pruning shears, also called hand pruners (in American English), or secateurs (in British English), are a type of scissors for use on plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required.
Cutting plants as part of gardening dates to antiquity in both European and East Asian topiary, with specialized scissors used for Chinese penjing and its offshoots – Japanese bonsai and Vietnamese Hòn Non-Bộ – for over a thousand years.
In modern Europe, scissors only used for gardening work have existed since 1819, when the French aristocrat Antoine-François Bertrand de Molleville was listed in “Bon Jardinier”, as the inventor of secateurs. During the late 1890s, secateurs were sold all over Europe and the US. Today secateurs are widely used by gardeners, vintners and fruit farmers.
The world’s first anvil pruners were developed and produced in 1923 by Walther Schröder in Kiel, Germany. The pruners were given the product name “Original LÖWE” and were distributed internationally as far back as 1925. Other companies are producing anvil pruners, include Bahco, Edma, Felco, Fiskars Gardena and Wolf Garten.
Garden Pruner Pro. have only one blade, which closes onto a flat surface; unlike bypass blades it can be sharpened from both sides and remains reliable when slightly blunt. Anvil pruners are useful for cutting thick branches; one can bite into the stem from one direction, swing the handle around and bite further through narrowed wood from another direction. The anvil is made of a material softer than the blade, so that the blade is not damaged when it meets the anvil. Suitable materials for the anvil are plastic, aluminum, zinc, brass, or bronze alloys. The blades are made from hardened carbon or chromium steels. The hardness of the blades is generally between 54 and 58 HRC. On an anvil pruner, proper cutting is assured even if the blade swerves slightly to the left or right during cutting. As long as the blade meets the anvil at the end of the cut and fits tightly against it, the material is separated. For this reason, the blades of anvil pruners can be ground thinner than those on bypass pruners. The LÖWE principle – a drawing cut made against a fixed support – combines a drawing cut with a pushing cut. This is possible because the blade lever and base lever are connected by an eccentric bearing. When the pruners are open, the blade is longer than the anvil thanks to the eccentric bearing. When the pruners close, the blade draws back slightly while it pushes through the material. This reduces the cutting force needed to make a cut still further. Because they crush the stem they are cutting, anvil pruners are best for use on dead wood.
Bypass Garden Pruner Pro usually work exactly like a pair of scissors, with two blades “passing by” each other to make the cut. At least one of the blades will be curved: a convex upper blade with either a concave or straight lower one. Some bypass designs have only one blade, the lower jaw being broad (like an anvil) but passing the upper jaw. The ratchet pruner, which can handle stems thicker than two centimetres, fits in this category. Because they make a clean cut without crushing, bypass pruners are preferable for pruning live wood.
Parrot-beak Garden Pruner Pro. consist of two concave passing blades, which trap the stem between them to make the cut. These are suitable only for narrower stems.
There are two different types of blades for pruning shears: Stainless steel and carbon steel.
In addition there are Garden Pruner Pro. shears that have titanium coating. have a high corrosion resistance, due to the protective chromium oxide layer that covers the steel surface after heat treatment. On the other hand, they are not durable for long. has a higher carbon content, which gives the steel a lower melting point, more malleability and durability, and better heat distribution. The disadvantages are the quick corrosion and staining. blades offer a balance between durability, sharpness and anti-corrosion. Titanium is stronger, has higher corrosion resistance, and has about half the density (weight) of steel. The titanium coating helps strengthen the blade and prevent corrosion, and after being sharpened a few times it will expose the steel edge underneath, giving the best edge with higher strength and resistance to corrosion over the length of the blade. The titanium coating is recognized by the gold colored blade as opposed to the typical silver colored steel blade.
