Hey Doobin. "im not a carver".... then it might be hard to understand the issues...
using a chainsaw to cut wood in half is safe, you use the main part of the bar, you dont go anywhere near the tip and so kickback is highly unlikely, its a simple straight cut and assuming you dont pinch teh chain nothing can go wrong
when you are carving with a chainsaw you are rarely doing simple 'cut it in half' cuts, you use all of the bar including the tip a lot, you do a lot of plunge cuts, a lot of full depth penetrating cuts, a lot of half or partial depth ones too, you use the saw on its side and upside down, you use the side of teh chain a huge amount and you are chucking that saw around all the time. so many things can go wrong, teh chances of the tip touching something is huge especially in complex pieces, damaging the piece and making the saw buck like a mule. unlike simple logging-cuts you cant just let the saw do the work, you have to guide the saw and sometimes force it to go against the 'easy path'. this is why we use small saws when we can, its why we dont use standard bars if we can possibly avoid it and why we dont tend to use full chisel standard chainsa and if we do use a standard chain the chances are we have modified it to work with our carving bars.
its teh same when we use other bits of kit... a rasp-grinder (flat-burr disc, rotating plane-discs and all of that sort) are great tools and if you are working on teh flat with them and you have the guards in place then yes, they should be nice and safe BUT... its nto often that you have simple flat surfaces when carving. the chances are that you have complex shapes and that brings in big chances of teh disc touching an edge and kicking back. i suspect most accidents that carvers have with these tools are just that, the took touches an edge/angle and kicks and things go wrong. Im 99% sure thats what happened to me. i had on my gloves (which is the other possible cause, a thread or somethign from teh glove got snagged on teh rotating chain of the lancelot tool which dragged my finger onto the chain) and the guard but maybe the took touched a raised spot and dug in and twisted teh anglegrinder in my hand and it caught my finger. others have had the tool suddenly bight in and pull out of their hand, i even know of 1 man who was using an arbotech and it riped out of his hands and cut his thigh! luckily it missed his femoral artery otherwise he would have bled out in about 20 seconds!
we accept that carving is a dam silly dangerous activity but we do all we can to try to keep teh risks as low as we can. that usualy includes keeping knobs wel away from tools
hope that helps with the understanding doobin:001_smile:
