The chisel you see on the euro shoes is a lot different than the ubiquitous square toed, rubber soled shoes you see all over the place. The European shoes are either subtle, where the curve of the shoe transitions nicely into the chisel, or when it's more pronounced (like that first Bonafe pic) the toe seems to work itself into the wider part of the toe box smoothly. They also are less boxy overall, which tends to highlight their angularity.

The cheapo square toes look like crappy shoes with the toes cut off, futuristic clown shoes, or swim fins.

I usually stick with the almond-shaped toed shoes, but there is something very enticing about some of those more angular designs from carmina, etc. I think my next shoe purchase may stray into chisel-toe territory.
