K-tool vs. Officer's A-tool

[firefighterMV]

So we are looking into purchasing some "core pulling" forcible entry tools for our Aid Cars due to the increased need to force doors on EMS alarms. I want to know what your experience is with both and which you would recommend for this type of operation. We have the A-tool on our engines already, but no K-tools so experience with these is limited. Obviously, it is dependent on the lock and we are dealing with mostly residential occupancies so the deadbolts often have large "beauty rings" as I call them, unlike the standard small circular commercial locks. Thanks for any suggestions.

(This is the type of lock I would say is on the majority of our structures)

Three tools come to mind but my limited expierence doesnt mend me to recommending one over the other.

R-Tool, Rex Tool and A-Tool all available from firehooks unlimited.

Has anyone used the Mini-Pro bar? It says it has an A-Type lock puller. I like the design and want to know how well it works.

K tools tend to work better when the lock face is closer to the door surface.
A tools tend to work better when the lock face is further from the door surface, like the lock pictured.

I agree. Used the K tool many times in pre-rabbit tool days. When it fits it works fine. If it doesn't it's no bargen.
