atlantia is correct. handle is fine. you might just wanna polish the silver and swaasa with a silver polisher you can buy at jewelry stores, walmart, or krogers. i'd stay away from the Tarn-X brand tho. that's some potent stuff.
as far as the blade: etching is the process of removing a very, very thin layer of the blade to show the active lamination on the blade. before doing this, you must remove any oil that's on the blade first and to do that, you will need a 0000 steel wool and dish soap. wet the blade with warm water, apply some dish soap on it and just scrub it with the steel wool. that's it! rinse it after that. if you have acetone, you can apply this after cleaning the blade, to ensure all oil or grease is gone. looks like you have some grease closest to the handle... a fast way to find out if there's lamination would be to run hot water from the faucet on the blade. if there's lamination, you will see it appear before your eyes.
as far as etching; check this thread out:

you could skip the polishing part if you've already clean the blade. hope this helps...
