THERE ARE NO LOHAR IN EVIDENCE IN THE PICTURES BUT THE ICE BEING HARVESTED LOOKS MORE LIKE COMPACTED SNOW. A TRADITIONAL ICE PICK RELIES ON THE FRACTURE PLANES IN ICE AND IN THE HANDS OF SOMEONE USED TO USING THEM CAN HANDLE ANY SIZE OF ICE OUTCROPING OR LAKE SURFACE ICE(THE ICE WOULD ALREADY HAVE TO BE REMOVED FROM A LAKE IF IT IS VERY THICK AS A ICE PICK CAN'T DO THAT JOB).
THE LOHAR COULD WORK BETTER FOR CUTTING AND SHAPEING COMPRESSED SNOW AS SNOW WILL NOT FRACTURE SO IN THAT CASE IT WOULD WORK BETTER THAN AN ICE PICK. LOHAR WOULD NOT BE GOOD FOR ICE OR SNOW CLIMBING THOUGH AS THEY HAVE A SHARP EDGE ON THE BOTTOM WHICH WOULD SERVE AS A POOR CLIMBING ANCHOR. THE EDGE WOULD AID IN CUTTING THRU SNOW BY IMBEDDING THE BLADE FULLY AND THEN PULLING IT BACK PERHAPS GOING BACKWARDS TO MAKE A LONG SLICE IF THE SNOW WAS NOT TOO HARD. PERHAPS IT IS ONLY A TOOL OR PERHAPS NOT BUT IT COULD BE USED EFFECTIVELY AS A WEAPON ALSO.
I WONDER WHAT THE LARGE ICE CUTTER IN THE PICTURE LOOKS LIKE UP CLOSE. THEY MAY HARVEST THE SNOW/ICE AS A WATER SOURCE OR TRANSPORT IT TO TOWN TO SELL. AS WITH MOST REASERCH IT ALWAYS SEEMS TO BRING UP MORE QUESTIONS THAN ANSWERS ESPECIALLY WHEN YOU ARE JUST GETTING STARTED
MY USE OF ALL CAPITALS DOSEN'T DENOTE EXCITEMENT OR PASSION JUST POOR EYESIGHT ESPECIALLY WHEN IT COMES TO COMPUTER SCREENS
