I have owned literally hundreds of Solingen "Bowie" knives - that often were partnered with smaller ones such as this, usually people undo the Pommel nut and take the handle off and incorrectly put back the Leather and Composite + Brass Spacers - now quite often these were ever so slightly different in size as to taper with the shape of the handle - so people would .... 1, Replace the spacers in a different order or 2, leave a spacer or two out.
I modified a small pair of pliers to fit exactly the Brass Pommel nut - as the other guys have said you do have to be careful not to burr the nut.
I used these pliers because you could hold the two handles of the pliers and use good assertive pressure to undo/ tighten the Pommel Nut whilst the handle was
carefully packed while Viced.
Undo the handle again, clean up the thread - check carefully the spacers are in exact order for front and back order of colour & Brass, use Lock tight on the Brass Pommel nut again and tighten as hard as possible-while tightening it is MOST important to ensure all the packers/spacers stay in line - you may need a screwdriver handle to tap these carefully into place if they become slightly out of alinement ( before any REAL tension is put to the Brass nut ).
Your knife has had a hiding -the Aluminium Pommel has literally been bashed about - if done carefully you can re-shape this to the near exact shape as before - mind you you cannot take too much off the edge where it meets the packers as from factory these were perfectly matched in size for fit and finish - if not? try re-arranging the packers- (as long as you keep the order the same with front and back ) - sometimes only one packer will match the size of the pommel.
To me it looks as though there are a couple of packers missing - you can always sand the packers perfectly smooth if they are a little uneven once the knife is tight once and for all.
If you find - and you possibly will that the Tang will be slightly exposed and protrudes through the Brass Pommel nut - you can use a very fine file and finished with wet and dry Paper and no one would EVER tell that you have done this - if done correctly.
Stag Handles:
The Solingen Stag was very nice what they use, they came in two versions of Handles..... 1, two slabs that were 4 Brass pinned and used the same spacer / Packer system, and as you have the single piece rounder handle drilled through the centre.
I personally would not fill the centre of the Stag handle with Cutlers Cement - simply because if you do a good job of what I described above there is simply no need to.
The bigger percentage of the Solingen Blades were Stainless, and the Carbon Bladed ones were very hard to get in tidy state - I personally would NOT do anything more but finish you blade in 400 then 600 wet and dry and keep it good with Mineral Oil - (baby oil ).
Here is a nice trio of one of Solingens greats Anton Wingen ( note the middle has the two-piece handle as I described above )
The smaller of this trio believe it or not is extremely rare and hard to get - in any condition ) these are the 15, 13, and 10 inch.
