myers had brought a small but useful selection of tools , the iron parts clanking in a bag , to be supplied with wooden handles from the forest close at hand : a barking ax and another felling ax , a plowshare for the spring planting , augers , planes and chisels , a small grass scythe , two hammers and a handsaw , a peculiar thing called a `` twibil '' that jamie said was for cutting mortises , a `` drawknife '' -a curved blade with handles at either end , used to smooth and taper wood-two small sharp knives , a hatchet-adze , something that looked like a medieval torture device but was really a nail-header , and a froe for splitting shingles .
