All About Pocket Knives

Hi,
This is the first time for me in the forum, although I have been reading and learning from it for some time now, and like to thank all the participants for knowledge and information.
I have these 3 knives that came in a lot I purchased and I have no idea where they came from or their value.
Knife one: 10" long full tang, with a black bakelite or phenolic handle (like Buck 119). Stamp appears to say "G.ERISEN".
Knife two: 7 - 3/4" long Damascus full tang.The handle has a very nice wood (don't know what kind), and it has no name anywhere.
Knife number 3 looks like it could be from Spain or maybe Mexico from the stamp "Eliazar y Chelo", but I was not able to find any cutlery with that name. 10 -1/2" long. It is dated 2/5/97.
ANY INFO AND VALUE WILL BE VERY HELPFUL!
Thank you,
Joe N.

No idea who made them but I like em all, especially the first one.

Hello Joe, welcome to aapk.
We have many fixed blade pros here on aapk, I'm sure some will assist in answering your questions.

However, I can help you with your question on your number two 7 & 3/4" Damascus knife "Handle Material" It is: "Spalted Maple" and is technically not a specific species of Maple, but rather a general description of any type of Maple that has been allowed to begin initial stages of decay, and then subsequently dried (preventing further decay). Therefore, no two pieces of this wood is ever identical.
The partial decay, called spalting, gives the wood dark contrasting lines and streaks where fungus has begun to attack the wood. If the wood has been rescued from the spalting at the right time, the lumber should still be sound and usable, with little to no soft spots or rotten wood.
I know this, due to my years of woodworking, (hobby) I use this wood on occasion with my wood projects. Some pictures are posted below.
Same wood as your Damascus knife handle. It is a "Softwood" and rather expensive.

Thank you Dan!
Like I said, there is always something new to learn on this forum.
And thanks for the photos.

Thank you Sam!
