I know for a fact that most of my peers prefer Marshalltown trowels. These are great trowels for archaeology - strong and durable because they are forged out of a single piece of steel. The Marshalltown is legendery in archaeology and pretty much the only option for most archaeologists - heck, Kent Flannery even mentions them in the title of his "Parable of the Golden Marshall Town."
My problem - as a graduate student on a budget - is why not use a more common trowel. I have to mail order Marshalltowns, and before shipping they are already $15. Now, this may seem somewhat whiney, but I think that's entirely too much to pay per-trowel if I'm going to be offering a public field experience (and providing trowels to volunteers).
Kobalt Trowels (available at EVERY Lowe's Store) are another matter. While Marshalltown really makes only the best trowels, I can tell by just looking at the different options that Lowe's offers a wider variety of quality (or lack thereof). But there are a couple trowels, about $9 a piece that have attracted my attention. Like the Marshalltown, they are made out of a single piece of forged steel. The only real difference in material is the plastic/wooden handle on the Kobalt compared to the Marshalltown's wooden handle.
I bought one of the square 5' margin trowels to test in the field. Maybe it'll work, maybe I'll like its feel/balance while I'm in the field. Really, all I care about is that it doesn't fall apart easily. Even if it does, it's a Kobalt tool so, I'm not overly worried. If it breaks, I can take it back to Lowe's and exchange it because like all of their hand tools this trowel came with an unconditional lifetime warranty - a lot like the ones sold with Craftsmen tools at Sears. I've had family use it before, and apparently the procedure is rather painless so even if the trowel does ever break, I can take it back to one of the many ubiquitous Lowe's stores across the country and just get a new one.
Anyone else have thoughts on the idea of using Kobalt trowels in the field?
