It ain't...but if it were me, I'd return them and ask for my money back. I'm a firm believer in supporting suppliers and the people who support us but I'm also a firm believer in calling them to account when they screw up. Think of it like this....every dollar is a vote. If you pay them a hundred dollars for "substituted" goods, you vote to approve of their substitution. And the next time someone...me, you, Al, or some unfortunate beginner, orders from them, they'll be more likely to do it again.
I'd write them a letter and complain vociferously. Tell them these awls will not do...that they aren't a reasonable substitute if only because the awl will be weakend by the hole. And ask that they either replace the awls with what you actually ordered...at their expense, shipping included...or return your monies, shipping included. I know that's probably more hassle than it's worth, but it just that reluctance that they're counting on. For the good of the Trade...they shouldn't be allowed to get away with it.
Some years back I placed an order for pegging awls with CS Pierce. What they sent me was size 30 patcher needles that had been broken off and ground to a dull point. I immediately called them back and told them in no uncertain terms that this was tantamount to fraud and that I wanted my money back. I never got my money back despite repeated assurances that the "check was in the mail." But even though it was a small amount, I harassed them at least once a week for several months (on their toll free number) and, to this day, I tell everyone who'll listen that not to deal with CS Pierce because they are a bunch of crooks.
I'd hate to put Barnsley in the same category as Pierce but this is how it starts...
Sorry for the sermon.
