I don't believe there is a way to search for them yet.

What seems to be standard practice atm is to list your weapon and then a kit next to it, so searching for a weapon and whatever tier killstreak you want should work. You can also type into the little search bar at the bottom of the search page words like "specialized", "kit" or "*insertwhatever sheen you want here*" while having whatever wep you want in the item search box. The second method has worked best for me, but both are viable.

A lot of people aren't listing sheens and that can be helpful I would hope eventually in the options part that something that lets you indicate the sheen and possibly weapon you're looking for.

Listing what kit or fabricator and it's sheen or in the case of profession particle eye effect would be helpful. in the notes.

I've noted a tread on the market that looks to be a suitable pricing for kits, I have several nearly completed Specialized Fabricators I intend to sell once i get the normal KS weapons to craft them.

I dont think so as of yet, but I have seen people offer kilstreak items and in the want section they put keys and a kit to let you know its a killstreak item, much the same way they would put a strange part in the want section if their strange has a strange part

I was just wondering if anyone from the TF2 Outpost Staff could comment as to whether or not there are any plans to add the ability to search for killstreak fabricatiors, kits and weapons by their weapon type, killstreak effects and sheens? This is probably the single most requested thing to add to the site I can think of when talking to fellow traders given the number of players wanting to buy or sell killstreak items.

I'm not sure if the Steam API allows for these types of listings and searches, but if it does, it would sure be great to add this ability here. For now, I just go to the Steam Market to buy and sell killstreak items because I simply don't have the time to search through the hundreds of listings on TF2 Outpost.

I love TF2 Outpost. Thanks for the great site and hopefully we will see this feature soon!

or OP can get off their asses and add a feature that will allow us to select a kit effect.

Seriously, I doubt it would be that hard.
