Do any online knife vendors let you sort by washer/bearing pivot?

[metaphoricalsimile]

Bladehq seems to have the most useful filters (someone point me to another site if I'm mistaken!), but even there you can't easily see whether a knife has a washer or bearing pivot. Do any vendors allow you to do this? Is there another way to easily see whether a given knife has a washer or bearing action?

GPKnives gives a very detailed description of each individual knife instead of just lumping them together.

Eh, I looked up a knife that I know runs on washers and the description on GPKnives didn't say anything about whether it was running on washers or bearings.
