Le Marchant noted the lack of professional skill displayed by the horsemen and the clumsy design of the heavy, over-long swords then in use (the 1788 Patterns) and decided to do something about it.
Among many other things Le Marchant did to improve the cavalry, he designed, in collaboration with the Birmingham sword cutler Henry Osborn, a new sabre.
The hilt was of the simple 'stirrup' form with a single iron knucklebow and quillon, so as to be free of unnecessary weight; the intention of this was to make the sabre usable by all cavalrymen, not solely the largest and strongest.
[7][8] Officers carried fighting swords very similar in form to those of the trooper version, though they tended to be lighter, at around 1 lb 13oz (0.83 kg), in weight and show evidence of higher levels of finish and workmanship.
As a result of this there were many swords made which copied elements of the 1796 pattern design but incorporated a high degree of decoration, such as blue and gilt or frost-etched blades, and gilt-bronze hilts.
This was because they were fashionable, plus they were shorter and lighter than the pattern sabre..[11] The mounted swordsmanship training of the British emphasised the cut, at the face for maiming or killing, or at the arms to disable.
[12] A cut with the 1796 LC sabre was, however, perfectly capable of killing outright, as was recorded by George Farmer of the 11th Regiment of Light Dragoons, who was involved in a skirmish on the Guadiana River in 1811, during the Peninsular War: Just then a French officer stooping over the body of one of his countrymen, who dropped the instant on his horse's neck, delivered a thrust at poor Harry Wilson's body; and delivered it effectually.
The brass helmet was afterwards examined by order of a French officer, who, as well as myself, was astonished at the exploit; and the cut was found to be as clean as if the sword had gone through a turnip, not so much as a dint being left on either side of it.
