Blade shearing

Blade shearing or hand shearing is the style of shearing sheep and other animals with fibrous coats (alpaca, llama, goats etc) with a set of specialized scissors. It is practiced in many parts of the world as both an occupation and a sport. Commercial blade shearers shear on average 140 sheep in an 8 hour working day, but some will shear over 200 sheep in a day.[1]

History

Shearing the rams by Tom Roberts depicting blade shearing in Australia

Shearing is said to be one of the oldest occupations, as people needed fiber to make garments. Originally sheep and other animals were shorn using sharp glass or metal taking tufts of fiber at a time to harvest the fiber but slowly man adapted scissor-like blades to make the job easier. Machine shearing was invented in the early 1880's[2] and slowly took over as the main form of shearing, but there is still a place for blade shearing in certain environments and also as a sport.

Equipment

Blade shears are similar to scissors, although most have the hinge at the back of the shears rather than the center but some still have the hinge in the center e.g. Jakoti shears. Conventional blade shears can come with a single bow, double bows or inverse bows. Double bow shears are by far the most common as they are the most versatile. Single bow shears and inverse bowed shears offer more resistance and are mostly only used for tough shearing sheep. They come in varying lengths from about 10 cm(4inches) to 18.5 cm(7.25inches).[3]

Most blade shears can be used straight from the factory but they usually give a rough cut and most people wouldn't be able to shear for very long before wearing out their hand. Most blade shearers will either spend time 'doing up' their shears or buy already done up shears from other shearers. The process of doing up shears can take a couple of hours and consists of five main parts[4]

Specialized equipment such as pull-backs and pendulums for grinders are used for some of the processes above which come at an expense which is one of the reasons many people buy shears from other shearers. Another reason people buy done-up shears is due to a lack of knowledge about doing-up shears, as many shearers in countries, like England, would only use a couple of pairs of shears in their life so would not spend the time learning how to do up shears for this.

Once the shears are done up the shearers will still maintain the edge regularly. In most commercial shearing, shearers will usually sharpen every one or two sheep to keep the edge honed in order to make shearing easier. Shearers will usually use an oil stone or laminated diamond stone to keep the edge on their shears. As the stoning bevel gets too thick shearers will grind back their shears to speed up the sharpening process.

Occupational

New Zealand

In New Zealand, there are still approximately 40 commercial blade shearers who work between July and October each year. Between these shearers, 400,000 sheep are shorn each year in New Zealand, mostly in Otago and the Canterbury high country. Blade shearers in New Zealand usually travel to sheds in groups of 5 or 6 shearers and usually live on the station during shearing. Often they will stay on the station for up to a week shearing around 1000 sheep per day. Most of the sheep that are blade shorn in New Zealand are fine wooled Merino.

The main reason sheep are still blade shorn in New Zealand is due to the harsh climate at the time of shearing. Blade shearing leaves a thicker cover of wool on the sheep[5] after shearing giving it more protection from storms and also the wool grows back faster after blade shearing than machine shearing.

South Africa

Around 17million of SA 29million sheep are still blade shorn today. This is due to the relative expense of machine shearing compared to blade shearing. Blade shearing is mostly cheaper as a blade shearers equipment in SA is only valued at around R2,000 compared to a shearing machine which costs around R15,000.[6][7]

Australia

Most of the blade shearing in Australia is on stud farms, ewes and rams in order to leave more wool on the sheep or a more natural finish. Some farmers will also trim or shape their sheep using blade shears for showing at competitions.

The United Kingdom

In the UK there is still a small number of sheep blade shorn each year. Most of the sheep shorn are in Scotland or in rougher parts of the country where sheep have either been mustered late or they don't have the resources for machine shearing. Many people still also use blade shears for trimming or dagging their sheep. In saying this there are a lot of people in the UK who know how to blade shear but most would shear only a few sheep per year.[8]

South America

There is still some blade shearing in South America for Alpaca, Llama and sheep. Blade shearing is used for sheep in parts of Patagonia where the weather can be very harsh and so the extra cover of wool left by blade shears is preferable.

Sport

In blade shearing competitions, the competitors are not only judged on how fast they can shear but also how tidily they shear. International blade shearing rules stipulate that the sheep must have an even finish of 5-15mm of wool and shearers will be penalised for any skin cuts or any wool that is too short or too long. Shearers are also judged as they shear for any time they cut the wool twice, this is called a second cut.[9] Shearers can also be penalized for rough handling of the sheep or allowing the sheep to escape their control during shearing.

Blade shearing as a sport has been through some ups and downs since the 1980's but in the last 2 or three years, it has increased in popularity. In the last 30 years many blade shearing competitions have been discontinued but now, with a resurgence of interest, the number of blade shearing competitions seems to be increasing. There were only 3 blade shearing competitions in Australia 25years ago but that number has recently increased to at least 14 this year.[10] In the UK this year a show was created specifically for blade shearing and to promote the blade shearing circuit in the UK. This month (October 2016) the Boort show held a blade shearing competition with $3000 for first place, the largest prize for a blade shearing event in the world.[11]

The next big blade shearing competition is the world shearing championships in New Zealand, February 2017. Blade shearers from at least 13 countries will be competing including Australia, South Africa, Japan, USA, France, Germany, Ireland, England and more. For the last 20 years, South Africa and Lesotho have dominated the world blade shearing championships.[12]

Styles

Most commercial blade shearers in New Zealand and South Africa use a similar style of shearing to the traditional Bowen method([13]) used in machine shearing. The main differences are that in blade shearing the shearer takes less wool on the first leg of the sheep and they shear around the body of the sheep more than along the sheep.

In Australia Blade shearers usually shear around the sheep even more to leave a smoother finish. They even shear around the backbone instead of along it. This method is especially useful for when you are trying to leave a longer staple of wool on or on very skinny sheep with a high shoulder.

In several countries, they will tie up the sheep for shearing, this means that it is much easier to hold the sheep during shearing and means it cannot escape. This method is ok for less experienced shearers but is much slower so isn't suited for large mobs. There is a competition for this style of shearing at the Royal Welsh show each year[14]
