I am an experienced backpacker and Engineer and was looking for a lighter weight alternative to the standard Aluminum tent stakes. I live in a state that is mountainous and wooded (where its not clear cut). What I needed was a rigid but not brittle stake that I could use my hand to push into the ground without the stake bending. The smaller the diameter and the shorter the length, the less purchase power you have but you reduce the probability of spending too much time probing the ground trying to find a place to really sink the stake in. The shepherds hook design, requires full insertion (where the shepherds hook tip bites into the ground) or the stake can rotate and the guy line can slip off. Since light weight is more critical than purchase power(for where I will use these stakes) I thought I would give these a try. I searched exhaustively to find actual titanium "skewer stakes" (which these are not according to my research) so that I could increase the use of these stakes to included softer ground and still have good purchase. "Skewer Tent Pegs consist of a twisted square rod which provides improved holding power."
I chose the 5 gram option of titanium stake which weighs (5.7 grams, just under .20 ounces) and has a usable depth of insertion at about 5 inches (before the shepherds hook bottoms out). These stakes are about .12 inches in diameter.
If I were to re-engineer these stakes, I would make them a true "skewer stake" and I would put a nearly closed loop at the top instead of a shepherds hook for reasons noted above. If I were a marketing person, I would change the name by eliminating the term "skewer" in the product name as this might be considered misleading. The integrity of the populous is evolving and folks are more prone to support products that have fewer hints of perceived deceit.
