I am looking to try my hand at furniture with live edge/slab tops and have only an average car to transport what I buy. I'm hoping to find some 15" wide tops and would like to cut 10' lengths down to 4' or 5'. So the question is what cordless tool is best to buy (don't you dare suggest I cut it by hand.) Choices are circular saw and saber saw. My experience with cordless is limited to drills. Am I concerned about nothing? Can any tool easily handle one cut through 1-1/2" or 2" stock?

Thanks
