Your best bet would be to try to hold it in person before you purchase it. I have probably the definition of medium hands and I feel like a Domino would certainly work just as well if my hands were smaller. I guess my fingers may be just slightly longer than average, but I would say my fingers are slimmer than average. Worst case scenario try to find a used one that you wouldn't loose money on if you decided to sell it. Or you can order from a retailer with a good return policy. I'm personally not a fan of ordering a knife with the "I can just return this if I don't like it" mindset, but if you're a loyal customer and end up making many purchases from said retailer, I don't think it would be the end of the world if you shipped one knife back that didn't work for you. I'll pretty much always make the 40 minute one way trip to a knife store to try out some models before I buy one if I'm unsure about them. But if you don't typically buy from that physical store, this can also dip in to the whole ethical dilemma of trying a product at a brick and motor store and then buying said product online.
