Log splitting wedge

[B.S.F.]

Whilst looking for a second 10" log splitting wedge on the internet I've noticed that like my Hy Test, some have a groove on both sides. Is that groove important,
does it serve a purpose ? Thank you.

Having grown up with a combustion stove, boy was I glad to see the last of those things when I left home.
My understanding was the groove helped to keep the wedge on track down the grain.
We had two of each,certainly I know the smooth ones we had would run sideways.
Happy to forget which was best.

To expand on Glen's comment - the groove forms a ridge on each side of the opening made by the wedge, which acts as a sort of rail to guide further movement of the wedge. How effective this is probably depends on the type of timber.

I was gunna say it was to let the blood escape. 🤪

I've got about 6, three 10" and three 6". I also have a long handled maul for driving them. The head of the maul is made from a piece of ironbark from the demolition of the old Pyrmont bridge in what's now Darling Harbour.

Have you seen those things that look like a stepped drill bit. You use them with a large drill and if you look at Utube or whatever it's called, they make splitting timber look easy. Bunnings sell them.
