I have a Clip Point Recon 1. I find it useful for most tasks, an imagine that the Spear Point would be similar performance-wise.
Tanto points are useful for EDC, nevermind what others said. Prying, scraping, using the secondary point as a box/envelope cutter, stout and thick point for awkward and tough piercing tasks, and is a really easy shape when sharpening needs arise.
I love and carry many tantos, including the Cold Steel Gunsite Tanto, a Utilitac Tanto, a couple Ganzo, HARNDS, Enlan models and I have used many tanto fixed blades for camping and otdoors (namely the SOG Tsunami, a couple cheap RUI-branded tanto blades, a Ka-Bar tanto as well) and found them as useful as other more conventional blade shapes.
Except for carving.
Sure, the cool-factor is there, but don't discard this particular blade shape for EDC, defense and other knife related activities.
Depending on your intended use, though, you may prefer to chose other blade styles. If you could specify...
