I'm not going to talk about ethnic knives, or historic knives, I'm going comment only on why a maker would choose to use an integral bolster rather than a bolster or guard that is pinned and soldered.

If you pin and solder you need to drill through the blade.

Holes in blades create a weak point.

A bolster forged from, or fire welded to the blade has the opposite effect:- it strengthens the blade.

Its not necessarily because knives have a habit of breaking at the junction of blade and hilt, its just that an integral bolster is superior construction to a bolster pinned and soldered.

Then there is the factor of craftsman preference. If the maker is primarily a smith, it is easier for him to make a blade with an integral bolster than it is for him to fiddle around with drill/pin/solder. If the maker is primarily a cutler, it easier for him to drill/pin/solder than to consider an integral bolster. The cutler will get a forging that he needs to turn into a knife, a flat blade without the lump that needs to be filed to shape for a bolster is easier for him to work with.

I have made many blades in damascus with integral bolsters, I made custom knives and blades for a fairly lengthy period, about 20 years from memory, and I was an early member of the Australian Knife Makers Guild. I was primarily a smith, not a cutler.
