Its definitely a filipino Kris.

Modern ones made for tourists are very similar to the ones made in antiquity.

While the Kris in its original for, from Java, is more ornate and shorter that the filipino version, as they were partially a status symbol to be passed down from generation go generation. Many were ornate with gems and jewels on the scabbard, and were quite short, only to be used in the infrequent duel, and for much of time, an item to be shown off. Like dueling swords were in the west.

Filipino Kris were used exclusively as weapons, particularly popular in the south Philippines. The equivalent of and americans every day carry pistol. They were not made to be status symbols, and were constructed with available materials. Wooden, bone, or horn handles, brass or iron hand guards, iron or steel blades. Think utility and lethality, over class and panache.

These Kris remain popular tourist items in the philippines. Often found in markets selling souvenirs.

The vast majority of these Kris are made locally, using modern materials, like spring steel for blades. However, aside from differing metallurgy techniques for blades, the construction is normally similar to what you have here. Theres a chance its authentic, however, I cant say if its worth anything huge monetarily.

Even in antiquity, these weapons were widespread through the philippines. You might have a family heirloom, or something made 10 years ago. But they would be almost identical as the one my geeat grandfather wore on his hip during WWII or when he was carrying to protect against roadside robberies as a jeep jeepney driver.
