Mine are Pentax 8x21 UCF reverse porros. These were $140 MSRP (list price) back in the 80's. They are not the same as the 8x21 Pentax makes today which are cheaper in cost and in performance. Mine weigh 7.5 ounces. My next size up are Leopold Yosemite 6x30 which weigh 17.5 ounces.
In terms of handiness the little binocular of these two is I would say fifty times more handy.
Everybody in my opinion needs at least one really really tiny binocular. Even the case and strap will be less cumbersome because even a shoestring for a strap will not irritate your neck when the device weighs under 8 ounces. That's all the strap you need. A shirt pocket that button downs can serve as the case.
The only advantage of the 8 power Yosemites are wider field and brighter images. The image is actually better on the tiny 6 power Pentax and being so very tiny in weight the 'shake' is less when viewing stars than on the lower power Yosemite. But remember brightness is way reduced, to say the least.
Larger binocs might fit the hand better, but when something is really, really, lightweight, it is going to be more comfortable and shake free despite not fitting the hand as well as a bigger binoc.
Just my opinion. Today, I would recommend trying the Pentax Papilio 6.5x21, although I haven't actually looked through one of those.
