That is fairly small for a even a keris sajen, but certainly not unheard of. I always find age rather difficult to determine with this type of keris. They have been making them for hundreds of years and there aren't really many stylistic variations that can act as indicators to different time periods here. Yours does not look new, but exactly what time period it was made i will leave for others to determine. Keris sajen are talismanic blades of rather plain and simple design and i am not aware of them being all to popular in the tourist market were people tend to look for a little more bling to remember their trips by. I would certainly not consider this a tourist item.
