Where Is Obi Wan Kenobi and Qui gon jinn's Lightsaber?

In Star Wars Episode 1: the Phantom Menace, when Darth Maul kills Qui Gon Jinn, Obi wan kenobi starts a saber duel with Darth maul and Darth maul uses force push on Obi wan Kenobi. The latter Obi wan hangs on that deep and dark big pipe. Then, Darth maul kicks Kenobi's lightsaber into that hole. After that Obi wan uses Qui Gon Jinn's lightsaber to defeat Darth maul.

My Questions is

1. Where Is Obi Wan's Light Saber ? Does it build new or found that from somewhere like from bottom of that big pipe or etc.?


2. What about Qui gon jinn's Light saber? Where it is ?
