Hawkbills, or pruners, as they are known in the UK are very common and easy to get hold of in Europe... waynorth's display shows some old harvesting knives, very nice too.
This knife shape is Roman in origin, hence its widespread appearance all arouns Europe and the Middle East... I have some old grape harvesters from Lebanon, made in the 19th century... no pics I am afraid, they are at my Dad's house.
There are a lot of pruners still around that were made in Sheffield in the 19th and 20th century. Wrights still make them - with horn or stag handles, for about $40 or so. Also, there are lots on the UK ebay for sale - beware, some of them are old, but not really functional, they have been used to death and the stag is often split or missing and the old carbon steel blades are worn down from use. Those made by Wostenholm or Rogers or Slater fetch a good price, especially in stag.
Traditionally, in England, a hawbill is a gardener's knife, used for pruning roses, harvesting fruit and vegetables and just tidying up. It is probably the commonest traditional knife seen or used in England.
It has been replaced by the 'Stanley knife' - (boxcutter), which is now used by just about all electricians, plumbers, carpenters and carpet layers because it is sharp, cheap, safe to use and legal to carry.
Hawkbills are on sale in my local hardware shop in the village, German or British made, usually stainless, and almost always with rosewood handles. They go for about £12 - 20 for a good quality one.
