Just in general, not even EDC stuff but in general small metal consumer goods can very often be found offered in stainless steel, aluminum, and titanium. This is the exact order I bought my 3 camping pots in fact, and often any items can be found in the 3 different metals at 3 different price tiers.
Start with the common, inexpensive, durable, corrosion resistant, stainless steel which is used on many inexpensive consumer goods and can sometimes be a bit heavy and clunky. Aluminum is a bit more but relatively modestly priced, rigid, lightweight, corrosion resistant and used on a ton of widely ranged consumer goods. Titanium is super light, expensive, not very hard or strong (on the end product) but plenty enough, corrosion resistant, mufti-colored and used on mainly high tier and expensive consumer and enthusiast goods.
Aluminum is really very close to titanium when it comes to consumer goods and the much better value, there is no reason for the common man to really need Titanium as you spend a lot more to lose a little weight and also some strength. Though I don''t know which is really stronger, titanium or aluminum, maybe just that titanium products are often really made to maximize weight savings so they are a bit under built as well.
Titanium is just for lightweight things but switching from aluminum to titanium does not really save you any weight on a pocket item but it still cost more so it is just for a collector thing. Often top of the line and nice custom items will incorporate titanium just for looks/prestige.
It is a neat metal just to look at and hold. I do love Snowpeak Titanium mountain cookware, my spork especially has been going strong now (while abused) for 8 years and is the perfect wilderness utensil but strong enough for a pint of Ben and Jerrie's back in town.
But I recommend everyone just forget about titanium though, it is just another thing to waste money on or wish you could waste money on that doesn't do anything.
