Splitting a Stone...Is Like Splitting a Log of Wood...Only "Harder"!

I have been thinking about the Drilled Holed Stones found and photographed all over Oak Island.
I still believe that on Oak Island there are stones used for directional markers aiding with the location of where the Tunnels and Treasure Vault maybe located, such as those at Nolan's Cross.
But... The recent findings on Episode One, Season 6, showing stones with drilled holes located on the Western Side of the Island, has me perplexed.
The Show has tried to explain these stones as some sort of mechanism for moving cargo by way of a chain pulled through a circular pin pounded into the drilled holes.
One of the stones drilled holes has a metal spike pounded into it, which they described as a support part.
Although, Stones on the Island could have been placed and used by the Depositors for Directional Markers, there could be a more logical reason how these Drilled Stones came about and possibly from a more recent date.
When I was a boy on the prairies, my summer job was Rock Picking
This was a back breaking job, clearing the rocks off a field to enable planting.
I came to appreciate the heavy weight of stones and the importance of their removal by the farmer.
At Oak Island, the Land Owners of the 18th and 19th Century may have found the best way to remove and use the stones for housing, fencing or roadways was to split them into smaller pieces.
This method was called...Plug and Feather - "
Plug and feather, also known as
plugs and wedges,
feather and wedges,
wedges and shims,
pins and feathers and
feather and tare, refers to a technique and a three-piece tool set used to split stone."
https://en.wikipedia.org/wiki/Plug_and_feather
"Each set consists of a metal wedge (the plug), and two shims (the feathers). The feathers are wide at the bottom, and tapered and curved at the top. When the two feathers are placed on either side of the plug, the combined width of the set is the same at both ends."
Technique
Multiple sets of plug and feathers are typically used to split a single, large piece of stone. The stone is first examined to determine the direction of the grain. After the location of the intended split is chosen, a line is scored on the surface of the stone. A number of holes are then cut or drilled into the stone face along the scored line approximately 10 – 20 cm apart. Plug and feather sets are then inserted in the holes with the "ears" of the feathers facing the direction of the desired split. The plugs are then struck with a small stone maul in sequence. An audible tone from the wedges changes to a 'ringing sound' when the wedges are tight. Between each series of strikes, a pause of several minutes allows the stone to react to the pressure. Eventually a crack appears along the line that was scored on the surface and the stone splits apart.

I hope the Show has the Metal Spike located in one of the drilled holes, analyzed as to its date of origin.
