A Spanish hairdresser has taken alternative styling to the next level, using swords, fire and 'finger scissors' to cut his clients' hair.

Alberto Olmedo, who has his own salon in Madrid, admits his methods are 'a bit medieval', but claims it is the only way to get both sides of a haircut 'mathematically exact'.

A video of Olmedo cutting his clients' hair shows him using a blow torch at a temperature of 1,300 C (2372 F), to shape a do.

Bold statement: Olmedo claims that his is the only haircutting technique which is 'mathematically exact'

Another woman is subjected to his 'samurai technique' as he uses not one, but two, sharp swords to chop away at her long hair.

'Hairdressers usually cut one side, and then the other, and one side is always a bit different from the other,' he says.

'Even if it's only a little bit.

'The only way to it in an exact mathematical way is to cut both sides simultaneously.'

Unusual methods: Olmedo also uses a blow torch to create shape and 'finger claws'

Which he does by wielding samurai swords and using a mini blowtorch.

He also favours a pair of claw-like scissor tools which fit on his fingers a-la Edward Scissorhands meets Wolverine.

'It's a bit medieval,' he adds.

'Sometimes you have to use a bit of your imagination to get positive results.'
