My grandpa’s(raised me) knife

My grandpa passed away in 2022 the year after I got out of the army, and when I had gone home for his memorial service, I took his knife of his table in the garage. I remember him having this when I was a kid and he would take me camping and fishing. Blades are dull as can be and it’s a pain to get the individual tools and blades open but this is the one thing I have from him as every thing else went to my mom and uncle. Which my mom and I don’t get along so. Likely the only thing I’ll ever get.

I was wondering what I should do to clean/ repair and if there is anywhere that I should take it to give it some TLC and sharpen the blades. (I live near Seattle) thank you guys for any advice/ recommendations.

Also, any of you knife fanatics, what year do you think this knife was made or is there any where on the knife that it might have a year on it.
