This is a Horstmann Knights Templar sword. To avoid any confusion, this is not a medieval sword used by the Order of the Knights Templar. What you see here is a beautiful ceremonial sword used by a Masonic organization, probably in the 19th century. The Latin phrase “In Hoc Signo Vinces” is a classic Templar motto.

Peter Johnsson (who works as designer for Albion) modelled it on a type of sword being used at the end of the 1100s. A well-known representative of this type exists and is preserved in the Kunsthistorisches Museum in Vienna: the sword of Saint Maurice, part of the imperial regalia of the Holy Roman Empire.
Arn was given his sword by his master and mentor, monk and one-time Templar, Brother Guilbert.
The sword bears an inscription “In hoc signo vinces” – “With this sign though shall be victorious.” This motto is not exclusively a Templar device, but it was somewhat favored by the Knights of the Temple.

For a very serious Templar buff, there are functional swords, such as this one by Marco of Toledo:
