I would get something with a guard. If your sister is not familiar with the knife, Eriksson 711 would be much better. She could be cut pretty bad if she loses grip on the handle.
God Bless
I think the first lesson I would teach somebody is how to keep a grip on a handle...how to keep the edge and the point away from the body...how to avoid a situation where a slip would end up sticking or cutting the flesh.
I know from experience and I have the scars to prove it
Edit: We have to remember that Moras and puukkos without guards were designed to make draw cuts, so the force of the hand is always moving away from the blade. A push cut forces the hand towards the blade and requires paying attention.
If tang length corresponds in any way with durability, here's the oft-posted picture of some popular models.
Mora makes knives that perform well beyond the price paid for them.
I have several.
I suggest getting your sister the Mora Craftsman "Triflex" model #780. It has a decent enough guard and is an outstanding using knife that has a hard edge and a soft back draw. This knife is my favorite Mora followed by the Carbon Clipper model. I like it for the guard and the fact that the knife, with that softer spine, can take a bit of abuse and it doesn't cost much at all. Try one and I'll bet you'll load up on'em.They are very good knives for the money.
I haven't had experience with the #1. I just thought the "Triflex" would suit your sister better since she's developing arthritis. I pray it heals and I hope the knife you give will serve her well.
