So I'm curious if anyone can tell me the difference between some of the model designations on the Kraftform 300 Series. I'd like to understand the difference so I can know what I need when I decide to buy. I know there are couple of Wera guys out here. Theres little difference in descriptions...

For instance for flatheads you have:
335
334SK
334
378SB

And a few for Phillips as well.

Thanks all!

Yeah, the difference between 335 and 334 is very minimal. 334 are just generally larger. They both have round shafts though.

The 335 has "Electrician's Tip" (Cabinet) while the 334 is "Workshop Tip" (Keystone.)

The 334SK has a hexagonal shaft with a bolster.

And anything that has SB on it generally means it comes in a retail package, in this case a hanging tab designed for display in retail environments.

Hope that helps!

Woody, I've been to the website, I guess I'm just looking for explanations of the different features. Hex shaft is different from a round shaft how (use a small wrench on it I guess?) and what's a bolster?? Different tip designs and their appropriate applications? First I've heard of a Keystone tip KCT.

I'll go to YouTube and see if I can find a video on flathead designs...

LOL I'm pretty well versed in tools just not the intricacies of screwdrivers and their design I suppose. I know all about hollow ground tips for gunsmithing however...

All I've ever really had were CMan and apparently they are vary basic...

As much as I hate to show you an image from a competitor's website, it's hard to beat this comparison of the two tips:

Yes, the hexagonal shaft is a little beefier and you can use a wrench on it. The bolster is another hexagonal area where the shaft and handle meet that is truly intended to put a wrench on. It "bolsters" the power you have to add torque to the driver.

Here is a video we made comparing the different Wera screwdriver lines (broader than what you are looking for) but at the time stamp you can see the bolster in action.

KCT, thank you so much, the differences were not so obvious on Wera's site. Any particular advantage of a Keystone tip vs a Cabinet tip? Seems a keystone is more versatile if you want to poke prod and pry stuff with it?

Edit: I reread your post and I believe thats what you were eluding to...
