“Skidproof” screwdriver

[OuBallieParticipant @ouballie]

Maples & Sons

6.1/2" long with a nice wood handle and unusually ground blade.

Ibe never seen one ground in this fashion, hollow ground yes.

Marples & Sons

[Chris Evans 6Participant @chrisevans6]

I have one of those, it was my Fathers. He always called it a cabinet screwdriver. I must search the boxes and find it. I still have his Marples wood chisels, they keep a superb edge.

[Colin HeseltineParticipant @colinheseltine48622]

My father always taught me to hollow grind the blade of screwdrivers. They always lock into the slot in the screw, rather than use the taper of the blade to twist out of slot.

London pattern usually has an all flat blade and flats on the handle too. Also usually in the larger sizes

Whoever said cabinet screwdriver had it right

[Phil PParticipant @philp]

Am I seeing the blade hollow ground cross wise and not lengthwise as is more common.

I think this is the point the OP was trying to make, we have all seen hollow ground ones done lengthwise, but I have not seen one ground like this before.

I would be interested in seeing a photo of the tip end on.

"Skidproof"? Get a "posi-drive" and use modern screws! I know, I know – they are not as aesthetic as slotted brass. And cheap screws and screwdriver tips are rubbish.

All 'proper' screwdrivers (cabinet makers, gunsmith etc) called them something else. Turnscrews was the name and many were made to fit their own bespoke slotted screws.

Ordinary screwdrivers likely did not need to be precise – especially after the invention of the Birmingham type – along with soft steel screws which were made for single use only!

The only good thing going for slotted screws is that paint is more easily removed from the slot than posi or torx, etc.

If you can easily file the screwdriver tip parallel, it is probably carp quality. Tips for 'lectric screwdrivers usually have parallel tips, btw.

Who is now going to make a quality screwdriver, like yours, and expect it to sell these days?

I too am curious how the skid resistance is achieved?

I recall seeing screwdrivers some time ago that had fine 'serrations' across the driving faces of the tip that were supposed to stop the blade sliding out of the ends of the slot. Not sure what the manufacturer described them as, but think it was 'anti-skid'

Modern take on the nonslip screwdriver

[Ian S CParticipant @iansc]

I have seen small containers of diamond grit in a paste for use on the tip of ordinary screwdrivers to prevent slipping.

Given up on getting that video uploaded for now.

Geoff – %^*+ computers!

[OuBallieParticipant @ouballie]

Oh, just noticed a milestone for me.

I've passed 1000 posts without noticing.

Been very very lax of late, so time to either update my car thread, or start a general one showing progress on the Austin.

Geoff – Thoughts please, Yes or No.

[Howard LewisParticipant @howardlewis46836]

Geoff,

Yes go on and show/tell us about you progress on the Austin.

Now, with longer days and better weather, you have no excuse!

Put us armchair engineers to shame.

having just upgraded the computer, know EXACTLY what causes high blood pressure.

Would "Hit Any Key When Ready" if I could find a big enough hammer!

[MikeParticipant @mike89748]

Time was when, for working on shotguns, I always used to make my own screwdrivers. Then I got lazy, and used to buy good ones from Britool or Snap-on. Now I just buy the best Chinese make I can find. The thing is, I always re-grind the points to hollow ground, no matter what they are to be used for.. When working on finely-engraved gun actions, you just can't allow a screwdriver to jump out of its slot, or you could cause hundreds, or even thousand poundsworth of damage. When working on stuff like this it makes sense to re-grind a screwdriver to fit an individual screw. I just can't think why all screwdrivers aren't supplied with hollow-ground points. Screwdriver bits for electric screwdrivers are, in my experience, always hollow ground – not that anyone would be daft enough to use an electric screwdriver on a shotgun.

OuBallie, let me echo Howard Lewis's comment – you do put us armchair angineers to shame!

Mmm … Interesting

Must confess, I don't recall seeing that suggested before

I suppose the sideways grinding on Geoff's screwdriver is intended to have the same effect.
