The medieval Baselard dagger was very popular throughout Europe from Italy through to Scotland and everywhere in-between, but strangely, they had two very different forms. In England and Italy the dagger had a very 'capital H' form and this is a classic example of this type.
The two arms are 'pinched' out from the same width as the blade, so the grip is quite narrow and the blade quite wide, and usually with either a fuller or a flat, so the blade transitions from a diamond to a hexagonal form near the hilt.
These were current and common all through the 14th and 15thC from the low born like Wat Tyler, through to knights and their effigies.
