I have two Double Cut users...one with Busse's own finish which is my FSH user and the other is a NMFBM which I had done over here...
Really to be fair to your question the FSH is the best one to look at...as there may be a lot in how the process is applied...
The finish does show scratch marks...it cannot be helped as it is a powdered coating finish which can be scraped away...Skunk I think said the same over a D/C SAR 8 he used in a recent post...here are some pic's of my FSH where the coating has been caught from using a ferro rod....
The coating can also show some kydex rub after being inserted and removed from the sheath a number of times...
You can remove the marks in part with either Flitz or WD40 and cleaning the blade although the "Matt" aspect of the D/C finish is lost and the blade starts to take a bit of a ghetto satin type of "sheen" where the marks were.
One answer is to treat the whole side of the blade and take the powdered layer off leaving a dulled "grey steel" effect but if you got this finish to avoid glare from the blade for a military role then becareful that the blade can still shine in bright sunlight...
However once it reaches this stage it is very stable and can be easily cleaned with washing up liquid and hot water and a scrubbing brush. It is just the same as Satin then...and if you needed to you could remove bad scratches with some wet and dry or a belt sander....gradually the edge becomes a bit of a ghetto satin over time although never seems to lose that "grey steel" look it has. To change it fully to satin you would need to use polishing belts on the sander...just as you would on stripping a combat grade finish...so it is not "fragile" and does make a good finish for a "user":thumbup:
It is not quite as easy as satin to restore to a perfect finish as the handle and spine and hilt often retain the darker "matt" finish.
However that is a good thing if the knife is sheathed and used in a military aspect...as it avoids glare from the pommel....but if this is of no relevance then bare in mind the blade can be a bit more "shiny" than the hilt.
You could of course clean the hilt and spine on the handle to give a uniform look if that matters to you....but I just leave it as is and clean the knife after use where it needs it. This FSH has seen some pretty hard use actually...but as you can see it cleans up well and is easily restored to looking good. Personally I think the D/C finish allowing for being a bit cheaper than satin is the best finish to go for:thumbup: If you are given the choice....
