'''Ice skates''' are boots with blades attached to the bottom, used to propel oneself across a sheet of ice.
The first ice skates were made from leg bones of horse, ox or deer, and were attached to feet with leather straps. A pole with a sharp metal
spike was used for pushing the skater forward.

== History ==
According to a study done by Federico Formenti, [[University of Oxford]], and Alberto Minetti, [[University of Milan]], [[Finnish people|Finns]] were the first to develop ice skates some 5,000 years ago from animal bones.<ref>[http://news.nationalgeographic.com/news/2008/01/080104-first-skates.html Bone Ice Skates Invented by Ancient Finns, Study Says], nationalgeographic.com</ref> This was important for the Finnish populations to save energy in harsh winter conditions when hunting in [[Finnish Lakeland]].<ref>{{cite web |url=http://www.timesonline.co.uk/tol/news/uk/science/article3090363.ece |title=Dashing Finns were first to get their skates on 5,000 years ago |publisher=[[The Times]] |accessdate=2007-12-24}}</ref> <ref>{{cite web |url=http://news.bbc.co.uk/2/hi/technology/7159057.stm |title=Skating traced back 4,000 years |publisher=[[BBC News]] |accessdate=2007-12-24}}</ref> The first skate to use a metal blade was found in Scandinavia and was dated to 200 C.E. and was fitted with a thin strip of copper folded and attached to the underside of a leather shoe.
In about 1859, [[James A Whelpley]] of [[New Brunswick]], Canada developed a skate that was well suited for long distance skating on the bays and lakes of southern New Brunswick.<ref> [http://www.rootsweb.com/~nbkings/Fam/JAWhelpley.html Biography of James A Whelpley]</ref>It was called the ''Long Reach'' skate, after Long Reach, a section of the [[Saint John River]], where the Whelpley family operated a factory manufacturing the skates. The skate had a steel blade about 40 cm long, on a wood platform that was attached by leather straps to normal boots.<ref>[http://www.musee-mccord.qc.ca/en/collection/artifacts/1963.94 Long Reach Skates at McCord Museum]</ref> The Whelpley family continued to make the Long Reach skates in New Brunswick, until about 1886, when the factory was moved to [[Keene, New Hampshire]].
== Design ==
[[Image:Sharpend_skate.jpg|thumb|Hockey skate being sharpened]]
Modern ice skate blades are not shaped like knives. The bottom of the blade has a crescent-shaped hollow, creating two sharp edges on each skate. Ideally, the two edges of a blade are parallel, but poor maintenance practices, such as improper sharpening or lack of consistent sharpening, can often result in oblique edges. These "bad" edges can affect skating ability significantly. The depth of this hollow is known as the Radius of Hollow (RoH). The Radius of Hollow is typically between 1/4" and 1" depending on the type of skates and the user. The optimal depth depends on factors such as the skater's weight, ability, strength, sporting activity, and (for ice hockey) style of play. The skater uses these edges in different combinations in order to maneuver. When ice skates are ''sharpened'' the blade is ground against a template either to restore the hollow or provide a different radius.
Speed skates and touring skates, however, have a completely flat bottom. There is no hollow, only a squared off bottom with 2 edges. This improves glide time by not cutting into the ice.
Inexpensive skates for recreational skaters usually resemble either [[figure skates]] or [[hockey skates]], but recreational ice skates resembling [[inline skates]] with a molded plastic boot are also available. These recreational skates are the form which can be rented from ice rinks for beginners who do not own their own skates. They are often called 'death wellies' by skaters who own their own equipment because of their appearance and their reputation for giving people blisters.
== Types of ice skates ==
There are five main types of ice skates, the figure skate, the hockey skate, the bandy skate, the racing skate and the touring skate.
=== Figure skates ===
[[Image:Figure-skates-1.jpg|thumb|right|Figure skates]]
{{main|Figure skate}}
[[Figure skate]]s are used in the [[sport]] of [[figure skating]]. They have ''toe picks'' on the front of the blade, which are usually made out of aluminum or steel. The toe pick has a variety of uses, but is most commonly used for certain [[figure skating jumps|jumps]] in figure skating, such as the [[Lutz jump]] and [[toe loop]]. Figure skating boots are typically made of several layers of [[leather]] and the leather is very stiff to provide ankle support.To lace them together you tie it just like sneakers.

=== Hockey skates ===
[[Image:Ice Skates Pair BW 2112px.jpg|thumb|right|Ice hockey skates]]
Hockey skates are used for playing the games of [[ice hockey]] and [[ringette]]. The boot is generally made of molded plastic, leather (often synthetic), and ballistic nylon. Skates used in competitive hockey rarely use molded plastic for the upper boot, as this results in limited mobility.

=== Goalie skate ===

Goalie skates are used by Goaltenders in Ice hockey. They are constrctued the same way as forwards skates are but are cut lower (similar to bandy skates). The blade is also set into a different kind of holder with a protective shell, called a cowling, this provides more protection then of a forwards skate.
<br clear="right">
=== Bandy skates ===
Bandy skates are used for playing the games of [[bandy]] and rink bandy. The boot is generally made of leather (often synthetic). The boot is lower than the hockey version, often not covering the ankles. All bandy skates are designed such that they will not cause injury to an opponent. The blade is generally an inch longer than the hockey skates, allowing for higher speeds. The Russian bandy skates have an even longer blade and a very low cut shoe.

=== Racing skates ===
[[Image:Clapskate1.png|thumb|right|Racing clap skates]]
[[Racing skates]], also known as speed skates, have long blades and are used for [[speed skating]]. A [[clap skate]] (or ''clapper skate'') is a type of skate where the shoe is connected to the blade using a hinge. Short track racing skates have a longer overall height to the blade to allow for deep edge turns without the boot contacting the ice.
<br clear="right">
=== Touring skates===
[[Image:Tour skate ice1.jpg|thumb|150px|Touring skate on [[ice]]]]
Touring skates (or Nordic skates) are long blades that can be attached, via bindings, to hiking or cross-country ski boots and are used for [[tour skating]] or long distance skating on natural ice. The blades are approximately 50 cm long with a radius of curvature (or rocker) of about 25 m. The blades are about 1 mm wide, with a flat cross-section. The length of the blades makes touring skates more stable on uneven natural ice than skates with shorter blades. Since tour skating often involves walking between lakes or around unskateable sections, the fact that the blades can be easily removed from one's boots is an asset. Although mainly used for non-competitive touring, touring skates are sometimes used in marathon speed skating races on natural ice.
