Sorry, noflyrule, I meant no offense. Occasionally some people visit this forum seeking essentially a Ginsu 2000 knife - one that never dulls because they don't know how to sharpen a knife and don't want to learn how to, thinking that modern metallugy can provide such a thing. The trident has AFAIK an AUS-8 blade. Assuming that it has a decent heattreat, it should be a perfectly acceptable bladesteel, meaning, while you are likely to see some improvements going to S30V or D2, the improvements in edgeholding may not be mind blowing. I just hope you are not going to be disappointed. Even the "supersteels" are easily dulled with a few swipes over very hard or very abrasive material. But maybe your Trident is simply defective (bad heattreat) or was run too soft.
The edgeholding will depend on several factors and which you can tune depending on your needs: If you cut a lot of abrasive stuff, you are best served with a steel that has high abrasion resistance such as D2 or S30V. Such steels contain often large carbides and have a large carbide volume which will in turn lead to low edge stability at very accute edge. Meaning a knife in D2 may outlast a different steel on lots of cardboard with a sturdy edge geometry. But it may be outclassed by the same steel on a similar application if you thin the edge out. You would thin out the edge to actually increase the edge holding and the cutting ability. But if you cut a lot of zipties and other plastics, you are IMHO ill served with a thin edge anyways because you are likely to laterally load the edge and it won't hold up. If you cut into very hard materials, the edge is likely to dull by rolling and you might have good experiences with a hard blade like one from ZDP-189 or SGPS. Scraping Aluminum is particularly evil (I deburr aluminum parts on occasion as well), because it forms an oxid layer which is very hard (it is actually used as abrasive) and tends to flake off or might get scratched off, so you might think of Aluminum as covered in an abrasive.
My suggestion would be a Manix aswell. Depending on your intended use you might want to keep in mind that D2 is only marginally stainless. It should stand up just fine in most cases, but if you plan on using it in a very corrosive environment (sweat or saltwater), it might not be the best choice.
