I too, am not a huge fan of liner locks, but I think I can live with it.
Keep in mind, the OHT isn't a real Walker-style liner lock. It's really a slipjoint with an old-style "safety" liner tab.
On a Walker liner lock, a long tab on the liner wedges against the angled
rear of the tang, holding the blade firmly against the stop pin. There is no backspring; the liner tab provides all the stability for the open blade.
On the OHT, like on numerous pre-Walker locking knives, the backspring holds the blade both open and closed. A tab on the liner blocks the
bottom of the blade tang, but only if the tension of the backspring is overcome first.
IMHO the old-style lock may not be as mechanically strong, but is actually more secure, than a Walker-style liner lock, unless the latter is fitted just right. The angled tang of a Walker lock means that part of the force from the blade is lateral, in the unlocking direction, so that any slippage of the lock tab can result in complete lock failure. On the older style liner lock used on the OHT, the blade force is 90° from the direction the lock releases, so the only way for it to fail is if the locking tab suffers complete mechanical failure, i.e. is bent or broken off.
